As I’ve said, I do have problems with the dominance of radical leftist theory in academia. (Apart from anything else, it being crammed down my throat put me off it for years, and it took me a while to find the value in it.) But something gets missed in the attacks of people like Pinker and Peterson on this bubble of leftism: their attacks are importantly conditioned by their own situation, largely cloistered in the same small territory as the bubble. Recall that for the most part, we’re not even talking about academia as a whole, just humanities departments and student unions.
