Basically his only major pockmark is his accelerationist stance in 2016, a stance he has functionally rolled back. Otherwise, he is among the most prominent voices extending Marxist ideology to a postmodern framework, while rejecting the simplistic cold war ideas of Communism vs Imperialism which absorbs so much oxygen in many leftist spaces.
Oh, nevermind, I remember. He's one of the guys who enjoyed hanging out with Jeffrey Epstein for "financial advice" and definitely not to abuse any of Epstein's underage trafficking victims.
He's the guy mainstream media ignore most of the time but then trots out every four years because he always ends up supporting the corporate approved Democrat.
The irony here is that I actually know a good deal about Noam Chomsky, but you apparently do not.
Mainstream media is NOT a fan of him, as they're his primary target of attack (Manufacturing Consent), and he's NOT a supporter of corporate Democrats by any stretch.
You can criticize him, and dislike him, but don't lie about him.
