To add to your unpopular opinion; I believe a big part of this is because people on Chapo don't actually read theory, but only get snippets and extrapolations from other people. Oppose Book Worship is a great piece of literature, but it also gives anti-intellectuals an intellectual justification for being ass backwards.

I also think a lot of it is held up by purity testing. I like Hexbear, but it's pretty much had the same reputation on Lemmy as Reddit because we got a lot of people who think they're better than everybody else because they listened to a podcast or watched a YouTuber.
