I'm sure Jerry Coyne has heard of Occam's Razor.
So let's consider the issue of Jerry Coyne claiming to be on the left:
Each time I see a pingback from one of these conservative sites, then, I am ambivalent. Am I helping or hurting my own cause? Like all people who take my point of view, I have of course been called “alt-right,” “racist”, and even a white supremacist. I brush off those names because they’re just slurs that progressives who lack arguments use to tar their opponents.
It's always fun when Coyne or Pinker claim their critics "lack arguments," when both Coyne and Pinker live in air-tight echo chambers and refuse to talk to their critics. Pinker infamously went on a blocking tear on Twitter (he blocked me long before that) and Coyne will not post or respond to any critics on his blog.
What disgusting lying self-congratulatory weasels they are.
So let's look at the facts.
Jerry Coyne constantly promotes and supports right-wingers and racists.
He apparently thinks that those who believe Amy Wax or Steve Bannon engage in hate speech are ridiculous:
What is accomplished by convicting this guy and sending him to jail? Will it deter others from making ‘hate videos’? Perhaps, but the concept of “hate speech” is so slippery that such deterrence is unwise. Meechan, after all, was not calling for the Jews to be gassed, expecting to incite Jewish deaths. Remember that many saw, and still see, the Charlie Hebdo cartoons of Muhammad as “hate speech”, as they see the views of Steve Bannon, Christina Hoff Sommers, or Amy Wax as “hate speech”.
Like all the other ghouls he constantly aligns with, he hates the 1619 project. Probably because it teaches actual Black history, which he and the other race pseudoscience ghouls would like to erase so they can claim that Black failure to thrive in the US is due to inferior Black genes.
Jerry Coyne participated in racist anti-democratic Peter Thiel's CPAC for racists, where he demonstrated his alignment with notorious racist Amy Wax. While deliberately misrepresenting left-leaning biologist PZ Myers as just a blogger.
Jerry Coyne believes in racist race pseudoscience. But like his hero Steven Pinker, he's enough of a weasel that he won't come right out and admit it, or explain exactly what he believes about things like race and intelligence, but you'd have to be a moron to miss his sympathy with Noah Carl, one of the most far-right racists in the race pseudoscience business:
In the article above on his website, Noah Carl found one item I missed in the ASHG report. (Yes, I know of Carl’s infamy: he was fired from a position at Cambridge University for working on the connection between human race and intelligence: an ideologically taboo topic that was, in his case, also characterized as “poor scholarship”)
He grumbles about the kids these days and their newfangled words.
But I think Coyne's position on the political spectrum can best be illustrated by the fact that he attacks critics of Amy Wax and Noah Carl, but he has nothing negative to say about famously racist and famously anti-democratic and famously pro-Trump Peter Thiel. Although he will go so far as to quote his fave right-wing bloggers' commentary about Thiel's support for Trump.
Now from this should we conclude that:
Jerry Coyne is a leftist who just happens to love racists and right-wingers and race pseudoscience and hates other leftists and has nothing bad to say about a lunatic right-wing anti-democratic Trump supporter?
OR
Jerry Coyne is a cranky old right-wing racist who is so delusional that he thinks he's still on the left?
