I think that brainwashing is over-stated. It’s not like anyone outside those narrow fields within the humanities has any reason to actively push it (though my alma mater had a bunch of SJWs camping out in the civil engineering school to teach all the engineering professional ethics BS[1]), only people already biased in that direction would enrol in those degrees because they’re almost useless, and even in universities with breadth requirements it would only work on those too stupid to figure out how to play the game. For everyone else it’s just something to pay lip service to without actually putting any effort into.   To be fair, I got good marks even when criticising the basic premises of some of the assignments, though I never bothered to find out whether that’s because they accepted that my reports met the requirements of the mark scheme even if they didn’t like what I wrote  or because they didn’t notice me attacking the readings and assignments themselves and just skimmed through until they got to the references, which are minutely examined.
