Solutions To Retrograde Motion Practical Astronomy Focus Problems

 1) a) Compare the orbital velocities of Venus and Earth, if the sidereal period for Venus, T1,  is 224.69 d, and for Earth (T2) is 365.25 d.


b) Verify this by using a Table of orbital velocities for the planets - given in km/s 


Solutions:  

We have:   V2/V1 = (a2/a1) (T1/T2)

By convention we assign '1' to the inner planet (Venus) and '2' to the outer (Earth). We have a2 = 1 AU and for Venus (from Kepler's third law):

T1 = (224.69/365.25) yr. = 0.6151 yr.

a1 = {[T1]2}1/3 = [(0.6151)2]1/3

a1 = 0.723 AU

Therefore:

V2/V1 = (0.7234)(1/0.6151)

V2/V1 = 1.175

(b) According to a Table of Orbital Velocities in Astrometric & Geodetic Data:

V(Venus) = 35.02 km/s

V(Earth) = 29.78 km/s

Take the ratio of the velocities: 

V(Venus)/V(earth) = (35.02 km/s)/ (29.78 km/s) = 1.175

So, Venus' orbital velocity is 1.175 times Earth's which conforms to the result of p
art (a).


2.(a) Why doesn't the component  Vp cos (φ)   contribute  to the observed angular velocity of the planet, (i.e. in Fig. 1) ?

(b) What if the  angular velocity of the planet as observed from Earth is: 
 - (Vp - V)/ PE and parallel  to the orbital motion?

Solutions:  

(a) The  component, Vp cos (φ)  doesn't contribute to the observed angular velocity of the planet because the  component vector direction  (along line P'E')  is oblique to the motion vector (itself tangent to the orbit)

b) If the angular velocity of the planet as observed from Earth is:  - (Vp - V)/ PE and parallel to the orbital motion, then it must also be in a direction opposite to the orbital motion, and hence is retrograde at opposition.  (Since Vp < V )



"He Can't Take A Joke!"- Kimmel Roasts Trump in Return - And The Wannabe King Wants To Sue ABC Again

 

                                         Kimmel greets crowd clapping on his return.



"Our leader celebrates Americans losing their jobs because he can't take a joke." - Jimmy Kimmel last night

Jimmy Kimmel literally roasted Trump for the better part of his monologue last night, e.g.

Jimmy Kimmel EVISCERATES Trump in triumphant TV return

And predictably the 79-year-old demented wannabe tyrant couldn't hack it scribbling in his Truth Social post:

Bragging the "last time I went after them they paid out 16 million dollars".  But they will not bite this time around, butt munch. ABC- Disney now knows - and the people know - that if they go yellow belly against speech again Disney customers can just cut the streaming service.

 Kimmel also graciously referred to Erika Kirk who on Sunday evoked Christian grace and compassion by saying she forgave her husband's killer.  Not so Tyrant Trump who, made a seemingly unscripted remark that summed up the retribution campaign that has come to define his second term.

I hate my opponent and I don’t want the best for them.

But this was in keeping with his pugilistic, bombastic, Philistine - Ape style of politics - which includes inciting insurrections and pursuing retribution for his political opponents. As he is trying to do now by getting AG Pam Bondi to prosecute James Comey, Adam Schiff, Letitia James and others.  

This is the dirtbag pustule that 77 million elected and now we are stuck with until he either leaves office as a lame duck - or is removed when his dementia reaches intolerable proportions.  

The critical takeaway from the Kimmel episode is that push back is effective and is the key to preserving our free speech rights under the first amendment. Once that is allowed to be taken, we are on a downward track to mirror Orban's Hungary or even Putin's Russia.  That can't be allowed to happen.

Jimmy Kimmel makes TV history with an emotional defense of free speech - The Washington Post

Excerpt:

The conditions for Kimmel’s return remain mysterious. Did Disney totally reverse its (clearly manufactured) objection to his remarks last Monday and give him free rein? Kimmel remained vague, saying only that he and ABC’s parent company “talked it through.” He expressed gratitude, emphasizing that as much as he objected to his suspension, they really didn’t have to reinstate him and that doing so “unfortunately, and I think unjustly” puts them at risk.

The company’s strategy has indeed been difficult to discern throughout this mess. Yesterday, while fielding boycotts from opposite sides — one from conservative broadcasters Nexstar and Sinclair, which refused to air Kimmel’s return on their affiliate stations, and another from customers protesting Disney’s role in the erosion of First Amendment rights by canceling their Disney and Hulu packages — the company announced a price increase for its subscriptions.

Kimmel, by contrast, framed his return well, skillfully connecting his own role in the firestorm to other significant moments in TV history, particularly First Amendment battles. On Tuesday, in advance of his first show back, he posted a photograph of himself next to TV legend Norman Lear, who co-signed (and won) a First Amendment lawsuit against the FCC in 1976. And he opened his monologue by saying “As I was saying before I was interrupted” — a reference to Jack Paar’s legendary return to “The Tonight Show” after he quit over a network decision to censor him.

Tuesday marked the return of late-night comedian Jimmy Kimmel, after his show was suspended last week following threats from President Donald Trump's administration. And Kimmel didn't hold back in his criticism of the administration — or in his defense of the Constitutional right to free speech.

Kimmel began his show with an opening monologue mentioning Disney (which owns ABC) pulling his show off the air following remarks he made about "the MAGA gang" trying to "score political points" off of the fatal shooting of far-right activist Charlie Kirk. He thanked everyone for supporting him while he was off the air, including both his fellow late-night comics and even conservative voices like Ben Shapiro and Sen. Ted Cruz (R-Texas) for defending his right to speak regardless of their personal political views. He maintained that his comments were not about Kirk — adding that he abhorred Kirk's murder and empathized for his family — but about attempts to exploit his death for political gain.

Citizens' Backlash Beats Back The Right's "Cancel Culture" & Anti-Free Speech Thuggery - As Jimmy Kimmel Returns

 

           WSJ's Strassel: Performs public service distinguishing right and left cancel culture.
                                          Kimmel: Free speech preserved- for now

Kim Strassel,  in her recent WSJ op-ed, ('Back to Censor Culture', Sept. 19, p. A13) got it right when she sounded off  about the Trumpian Right's new found campaign for "cancel culture":

"By and large 'cancel culture' on the left meant social media shaming, threats of boycotts, walkouts, lost advertising and elite sneering that provoked the cancellations. But Biden's FCC didn't tell ABC to fire Roseanne Barr.  And no regulator pressured Spotify to ditch Joe Rogan. The right has learned how to use these pressure campaigns too (see the Bud Light reactions).  So progress was already being made."

She was correct, so why the need to drag in federal power to force media companies to come to heel? In its Monday editorial (‘Ted Cruz’s Finest Hour), the WSJ editors themselves may have set the tone, writing:

"Most Republicans are afraid of uttering even a syllable of disapproval about the Trump Administration, so kudos to Ted Cruz for noticing the danger from Brendan Carr’s use of regulatory threats to stifle free speech.

The Texas Senator used his podcast on Friday to criticize Mr. Carr, who runs the Federal Communications Commission, for his threats against Disney, its ABC network and its station affiliates if they didn’t punish Jimmy Kimmel. Disney then pulled the late-night host off the air “indefinitely.”

Would that the disreputable bonehead honcho Brendan Carr - now heading the FCC - had also read it before popping off his threats to ABC-Disney (to get Jimmy Kimmel off the air).  But Carr had already absorbed Trump's brand of authoritarianism by osmosis. Realizing - like Traitor Trump  - media owners (like the universities, law firms and other corporations) faced complex financial and political dynamics under the newly aggressive Trump 2.0 administration.  Which as we know wields outsized leverage over any entity dependent on federal regulation or financial support.

How did Trump mutate into such a god-awful dictator in the intervening 4 years he was out of power? Easy. First, Trump learned from fellow tyrant Viktor Orban in Hungary how he could gain control of the media.  E.g.

Trump’s anti-media blitz that led to Kimmel’s suspension is straight from the Viktor Orbán playbook | CNN Business

Then there are the bully boy tactics themselves used to crash norms and laws, given the corrupt conservo Supremes conferred almost total power on the orange fungus. Perhaps this aspect has been best summarized in David French's latest column (Sept. 22):  

Opinion | Crony Capitalism Has Reached a New Low - The New York Times

Writing:

"There’s a pattern to President Trump’s second term. He breaks the law and bullies his opponents — and yet he still wins. The examples are legion. He barrels through the First Amendment rights of law firms and universities, and they cut a deal. The chairman of the Federal Communications Commission threatens to revoke broadcasting licenses over Jimmy Kimmel, and ABC yanks him off the air. He files a meritless lawsuit against CBS, and the network writes him a huge check.

One of Trump’s most consequential victories occurred on Friday, when he reportedly reached a deal with the Chinese government to hand control of TikTok, the wildly popular social media app, to a consortium of American investors, including Oracle and Andreessen Horowitz, which are connected to the billionaire Trump allies Larry Ellison and Marc Andreessen.

In the process, he defied a law passed by Congress and risked American national security. All to preserve access to a social media app while he negotiated a deal that benefited his billionaire allies, pulling even more of America’s public square into MAGA’s sphere of influence.

 So there we have it. Alas, it may be too late to turn back the authoritarian tide now, given Russians waited too long when Putin went after puppets that belittled him.   They couldn't see then they're failure to act cost them their liberty- what little they had."

But  hold strain. ABC announced yesterday Kimmel will return tonight, for the time being beating back the Trumper fascists. Since ABC’s decision, at least five Hollywood unions, collectively representing more than 400,000 workers, publicly condemned the company. Meanwhile, hundreds of A-class celebrities including Tom Hanks, Meryl Streep, Robert DeNiro and many others, signed an ACLU letter condemning the move. Howard Stern announced he was cancelling his Disney Plus subscription and thousands of others have followed- many ordinary customers.  See e.g.

Disney Has Lost BILLIONS After Canning Jimmy Kimmel

The screenwriters’ union decried what they called “corporate cowardice,” and organized a protest last week outside the main gate at Disney headquarters in Burbank, Calif. Damon Lindelof, a creator of ABC’s “Lost,” said that if Mr. Kimmel’s program did not return from suspension, he couldn’t “in good conscience work for the company that imposed it.”  Other Disney actors, producers also threatened action, ‘No Kimmel, No work’.

Kimmel’s return tonight on ABC will make for one of the most anticipated episodes of a late-night television show in years. But what remains to be seen is the extent to which he has agreed to be muzzled. To tell the truth, his original mild comments criticizing Trump (NOT Kirk) - which got him suspended -were a total Trump misfire. John Oliver, a guest on the particular Kimmel show, said the same in his Sunday night HBO broadcast. See e.g.

John Oliver DESTROYS Trump & ABC Over Kimmel Firing

 So an entire 'storm in a teacup' was started by the MAGA Mafia, and its top thugs - Brendan Carr and Mob Boss Trump. But a concerted constellation of citizens threw a counterpunch - hitting ABC - Disney in its profit margins - to bring Jimmy Kimmel (and free speech) back to this embattled nation.

In the aftermath of the assassination of Charlie Kirk, President Trump and his allies are insisting — without a shred of evidence — that a vast left-wing conspiracy are plotting violent attacks in this country. Naomi Klein, in her book “The Shock Doctrine: The Rise of Disaster Capitalism,” popularized the term “shock doctrine” -- based on the economic term “shock therapy” -- theorized that in times of war, political turmoil, natural disasters, and one might add, assassinations, right wing forces will push forward their agenda, regardless of how unpopular it may be.

After 9/11, for instance, the Bush administration launched a perpetual War on Terror; after Hurricane Katrina, New Orleans lost public schools and hospitals while tens of thousands of Black residents were displaced. Trump’s narrative now risks becoming another such shock, weaponized to expand repression under the guise of security.

As corporate media accelerate their censorship of comedians and journalists, we must realize that we got to this dire situation because of old-fashioned, bipartisan corruption in Washington, D.C. The problem didn’t begin with President Donald Trump. It began long ago, especially in the 1980s and 1990s, when presidents of both parties and Congress decided to put the nation’s media system in the hands of a small number of ever-larger corporations.

Those corporations were big political donors to both parties. Enormous mergers were approved. Antitrust laws were ignored. Federal Communications Commission rules were changed, and caps on mega-ownership were relaxed or eliminated.

Practical Astronomy Focus: Angular Momentum Applied To Orbital Motion

 Angular momentum, along with Kepler's laws, is also critically important in planetary motion.  For example, the law of conservation of angular momentum applies to orbital motion - whether of satellites about the Earth or planets around the Sun.

For conservation of angular momentum L in an elliptical orbit (with ra  the radius vector at aphelion,  and  with rp the radius vector at perihelion)

 L = mva ra =  mvp rp

Or: va ra =  vp rp

In more concise polar form:

L = mr 2  dq  /dt   =   r p q  =  r p sin q 

Or:

=   rmvq 

The angular momentum of a planet moving around the Sun is constant. This is none other than a restatement of Kepler's 2nd law.

We can also write: L = va ra  sin q  =  mvp rp

For conservation of energy (Kinetic or mechanical K, and gravitational potential V):

E tot = K + V  = mv/ 2 -   GMm/r =  -   GMm/2r

The centripetal acceleration is also a key quantity in orbital motion:  

a= v2/r   = (r w)/r =  r 2

 We can refer to the diagram below for the origin of the centripetal acceleration and the related force:


The way that the centripetal acceleration (ac = v2/ r) arises is via the change in direction of the velocity vectorv. Thus, the acceleration is: D v/r   or:  (v – v)/ r, but the magnitude of each vector is:

|v| = rq/ t = r w

By similar triangles one would obtain:

D v/v  = s/ r  and   D v = v(s/r)  but s = (rq)/ t

So: D v = v(q/ t) = vw

And since: w = v/r then:

c = D v/ r = vw/ r = = v2/ r

 A key relation is that the force of centripetal acceleration is directly provided by the Newtonian force of gravitational attraction, with M the solar mass and m the mass of a given planet:

And: GMm/ r 2   =    m v2/ r

But Newton realized:

GM/ R2 = v2/R  and let: v = 2π/P,

 P being the period, whence:

GM/R2 = (2π/P)2 1/R

Or, in terms of P2:   P2 = (4π2/ GM) R3

Which is just the Newtonian statement of Kepler’s 3rd or Harmonic law.

The preceding can also be applied to the Earth -Moon system, or indeed any planet-satellite system. For this we simply replace the mass M of the Sun with the mass of the Earth,  ME   then if we set the weight (w =mg)  of an object on Earth's surface equal to the force of gravitational attraction, F, we obtain:

mg = GME m/ r2

Or: g = GME/r2

In other words, g is independent of the mass m on the Earth's surface. Now, what about objects actually orbiting the Earth, say like artificial satellites? In this case we understand that what keeps the objects orbiting is the centripetal (or center-directed) force, which is defined as:

F= mv2/r 

Or:

mRw2 = gr2 m/R2, so that for the angular velocity w:

w2 = gr2/R3, and:

R3 = gr2/w2


Interesting Application:

This would be to find R (= r + h), and thence h (altitude)  of the satellite if the period is known to be one day or 86,400 secs. Then, T = 86,400s and, solving for R (using same magnitude for r, g as before):

R = [g r2/w2]1/3

R = [(10 m/s2)(6.4 x 106 m)2 (86400s)2)/ 4p2]1/3

R = 4.24 x 107 m = 42 400 km

But we know r = 6400 km so  h = R - r

And h = 42 400 km - 6400 km = 36 000 km

Or h » 22 500 miles above the Earth.

We call such an orbit geosynchronous or "geo-stationary" because the orbiting body retains an essentially fixed position above a point on the Earth and its motion (velocity) in orbit matches the rate of Earth's rotation.

Note that what we have discussed applies to circular orbits for which the radius is constant. But what about elliptical? Go back to the conservation of angular momentum at the top of this post and how it confirms Kepler's 2nd law.

Supplemental Problems:

1) Find the velocity of said geosynchronous satellite which matches the Earth's rotation rate.

2)  Verify the conservation of angular momentum applies for a spacecraft in orbit around the Earth if its velocity at perigee is  10.7 km/ sec, its distance from Earth at perigee is  6.6 x 10 3 km, its velocity at apogee is  0.75  km/ sec  and its distance at apogee is: 9.3 x 10 4 km.  Find the period of the spacecraft.

How Did Charlie Kirk's Cheerleaders Miss His Use Of Sophistry? And My Own College Debate With A Sophist Colleague


           Notice for Harrison College debate, May 10, 1991. The Assembly Hall was packed.


 When I engaged in my last major debate: 'Demons - Fact Or Fantasy?-  at Harrison College in May, 1991, I always ensured my sundry attacks - against my HC colleague John Phillips - were based on his own claims. Not my perversions or distortions of them in setting up strawmen.  My opening statement set the tone for the debate:

"My opponent will insist that we need a Devil- or demons - to account for a host of unknown or "evil" phenomena, including so-called psychic manifestations. My contention is that such claims are unnecessary given we already possess ample artillery in the scientific arsenal with which to provide plausible explanations without the need to invoke "demons" as additions to reality.  This approach is also consistent with a long standing principle of science known as Ockham's Razor which basically says 'hypothetical existences are not to be increased without necessity.

Adding: 

 "My opponent will also undoubtedly quote some biblical references to you at length to entice you to believe these are substitutes for truth and facts. They are not. They are carryovers from a semi-literate age, wherein zero scientific input existed.  So I do not recognize any biblical documents as even historically accurate as even conceded by a number of religious scholars. Let us further bear in mind the Bible is not one book delivered from above, but sixty six books written by flawed humans over a thousand year period. And in that period multiple translators often found it necessary to put their own words into the mouths of the alleged scriptural authors. The Bible then is more fiction novel than history text and cannot be used to base the existence of the Devil or demons."

 As predicted, John began by offering numerous citations from the bible. He cited Mark 1:27 for example, to argue Jesus had the power to cast out demons from "demoniacs" (Those possessed by the devil).  If demoniacs existed, as demonstrated in the good book, then demons existed as well.  From his references he went on to assert that Jesus spoke on several occasions of the power of demons to possess men.

"This is not fantasy!" John exclaimed, "this is grim, fateful reality!"

Thus, he left himself open to an abundance of my own questions as a skeptic, prefaced by saying:

"In an age of micro-computers, satellite technology and genetic engineering it seems to me a regression to base reality on beliefs from the Dark Ages."

Then asking:

- How many of these demons or devils are there?

- What is their primary purpose?

- What do they do with their time and how do we know this?

- Where do they reside when not tempting or possessing humans?

-- How do I tell if a demon is near?

-   How do I know it isn't something else?

John, being who he is, took the bait. The purpose of demons, he argued, was to possess or tempt as many humans as possible to get them into "Hell". The number agreed upon was roughly two thousand, based on the number of fallen angels we know of. (E.g. Lucifer).  He then mentioned a Larry King show only a year earlier in which a priest appeared, describing at length an exorcism he performed and challenged Paul Kurtz- an atheist - to deny it.   

I had happened to see the episode too, fortunately, and recalled the topic was “The Devil.” Kurtz, along the same lines I used above, disputed that any such entity has ever existed, now or in the past. This was in contradiction to a priest on the same show, who claimed that he’d performed an actual exorcism of “demons”. (Some clips of the alleged exorcisms were included) But Kurtz never bit. He pointed out that it appeared the “possessed” person was being held down, and anyone held down would fight like hell to get up!

I also knew I had clinched the debate when John asserted:

 "The main mission of demons on earth is the temptation of humans. We know the number of demons created originally from fallen angels  was approximately 2,000."  

 I then asked John: "Seriously? Two thousand demons? How would a small, finite number of demons keep pace with an exploding population of humans?  Do the demons procreate?"

"No! Demons can't procreate, they are spirits!"

I replied: "Well there are now six billion humans on planet Earth which means those two thousand demons must work very hard indeed! Doing the math they have barely a nanosecond to tempt each human in a given day!"

This brought the assembly down.

 The parameters of that debate have been recalled anew as Charlie Kirk has come to the fore, in respect of his purported "debating skills." Namely a NY Times piece Tuesday by Ezra Klein:

Opinion | Charlie Kirk Was Practicing Politics the Right Way - The New York Times

 Klein actually claimed:

"You can dislike much of what Kirk believed and the following statement is still true: Kirk was practicing politics in exactly the right way. He was showing up to campuses and talking with anyone who would talk to him. He was one of the era’s most effective practitioners of persuasion."

But is the use of sophistry "practicing politics the right way"? Not when it replaces the use of logic for the purpose of reasoned persuasion with logical fallacies.   Sophistry is basically the cunning use of fallacious arguments with the intention of deceiving, especially a large audience mesmerized by the sophist's charisma.  Some examples picked up from various Youtube  debates are instructive, and each exemplifies how well-prepared opponents were able to overwhelm Kirk:

Charlie Kirk Gets Roasted By Professor And Everyone Loses It!

Charlie Kirk Has Views On Ab*rtion DISMANTLED By Medical Student!

Charlie Kirk Gets SCHOOLED By Oxford Student On Masculinity!

Other instances that show the sheer prejudice, effrontery and arrogance of Kirk, are  exemplified in these sound bites from his "debates":

"Happening all the time in urban America, prowling Blacks go around for fun to go target white people, that’s a fact. It’s happening more and more".– The Charlie Kirk Show, 19 May 2023

"If I’m dealing with somebody in customer service who’s a moronic Black woman, I wonder is she there because of her excellence, or is she there because of affirmative action?"– The Charlie Kirk Show, 3 January 2024

"If we would have said that Joy Reid and Michelle Obama and Sheila Jackson Lee and Ketanji Brown Jackson were affirmative action picks, we would have been called racists. Now they’re coming out and they’re saying it for us … You do not have the brain processing power to otherwise be taken really seriously. You had to go steal a white person’s slot to go be taken somewhat seriously."– The Charlie Kirk Show, 13 July 2023

The answer is yes, the baby would be delivered.

Responding to a question about whether he would support his 10-year-old daughter aborting a pregnancy conceived because of rape on the debate show Surrounded, published on 8 September 2024

We need to have a Nuremberg-style trial for every gender-affirming clinic doctor. We need it immediately.– The Charlie Kirk Show, 1 April 2024

America was at its peak when we halted immigration for 40 years and we dropped our foreign-born percentage to its lowest level ever. We should be unafraid to do that.– The Charlie Kirk Show, 22 August 2025

"The American Democrat party hates this country. They wanna see it collapse. They love it when America becomes less white".– The Charlie Kirk Show, 20 March 2024

A recent Daily Kos contributor nailed Kirk's basic shtick:

"What is noteworthy about Kirk’s supposed “debate prowess” was his penchant for flinging wild assertions without any supporting  evidence, his apparent ignorance regarding who has the burden of proof, and his use of logical fallacies. For example, his banner at the Utah campus proclaimed, “Prove Me Wrong.” No, the burden of proof is on you to prove that you are correct. No one has any obligation to disprove an unproven claim. His proclamation was based on illogically shifting the burden of proof."

While physical claims are supported by data and objective evidence, the supernatural ones can only be accepted on faith, or the belief that some Textual authority said so.   However, this commits the logical fallacy of appeal to authority. - a point I tried to convey to John Phillips in our 1991 debate. A peculiar element of all spurious existence claims is that they can never be disproven no matter how many counter examples are provided. This is because metaphysical claims require the would-be “disprover” to go or be anywhere and look everywhere.  (I.e. “Prove to me there’re no Brontosaurus ghosts anywhere in the universe!”) 

Consider the following existence claim:

There are two- inch high green fairies that speak Greek and give out money for lost teeth

This statement is impossible to disprove, but that impossibility doesn’t mean it’s true.  The point being that the burden of proof rests on the believer or claimant given he is the one adding to existent, manifest reality. In other words, you can't say anything you want - irrespective of the topic-  and not back it up if you wish to be taken seriously.

Beyond that the fundamental tenet of all debates is that it is impossible to prove a negative.  This inverts logic, and renders the claimant in a near unassailable position as when Kirk prefaced all his encounters with the "Prove me wrong" bollocks. No, no one has to prove you wrong. You have to prove your claim is air tight, unimpeachable!

Same point I drove home in my debate at Harrison College. The onus is on the claimant to prove his case or at least provide the necessary and sufficient conditions for why it must hold. This Charlie Kirk consistently failed to do.

This brings up the latest piece (yesterday) from anti-elite troll Barton Swaim. In his forlorn WSJ column, ‘The Left’s Vast Lack Of Knowledge’, Swaim barks

That voters are sorting themselves along lines of educational attainment is the most salient fact of American politics in the 21st century. The credentialed vote mostly Democratic; everybody else plumps mostly Republican. You might be tempted to deduce that liberals and progressives know more about their conservative opposites than vice versa. You would be exactly wrong, as the fallout from Charlie Kirk’s assassination reminds us by the hour.

The day after Kirk was killed, the New York Times ran a story headlined “Where Charlie Kirk Stood on Key Political Issues.” The authors pieced together quotations manifestly taken from websites unfriendly to Kirk and made no attempt to convey the context or intended point of the various reproduced assertions. A section on antisemitism made Kirk, who’d been dead less than a day, sound like a Jew-hater of the 1930s."

The point missed by Swaim is that Kirk was often caught out in his actual denigrating remarks - see the Youtube videos. Failing that, Swaim needs to check out the following analysis by an Ethics professor. Yes, she's an "elite", Swaim. but I challenge you to see her make the case that Charlie Kirk is exactly the person we on "the Left" depict him as.

For instance, here I am, sitting at my desk, looking out my window on a beautiful, blue-sky afternoon. The leaves on the tree in front of me flutter in the breeze. A woman in a red coat walks through the parking lot, which is mostly empty. Everything is calm. The time is 2:43 pm on a Tuesday. This all seems simple enough, right?
