Here’s my guess: Pinker writes sometimes on evolutionary psychology. A controversy I heard around the atheism plus days was that evopsych should be banned. Therefore it’s likely that Pinker has been declared cancelled. Thus, to mention his name is to sin, and a sinner must repent, so wash your mouth out with soap and divert yourself from this path of heresy lest you join him.
I just don't see Pinker and Dennett as remotely connected. They don't work in the same field, they don't have much to say about the things the other is interested, and they were not even really on the same page w.r.t. "new atheism".
Hm, let us see. 10 seconds on google and wikipedia revealed:
"Steven Arthur Pinker is a Canadian-American cognitive psychologist, psycholinguist, popular science author and public intellectual. He is an advocate of evolutionary psychology and the computational theory of mind."
"Daniel Clement Dennett III is an American philosopher, writer, and cognitive scientist whose research centers on the philosophy of mind, philosophy of science, and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science."
