I once entered a “safe spaces” Discord server with literal flowers and stuff. It looked very innocent and welcoming and it was just for gaming. Turns out, they were making fun of their members on it, fake-crying to mock a depressed user, and kept telling the users to “let them see their cuts”. It was so disturbing. These were literal 18-20 year olds, too, and I was like 13.
I don’t know that I would personally make so many specific conclusions or necessarily group individuals together like that, but… as individual points I’ve no doubt that they do accurately describe various types of thinking and character.
I would also tend to think that if that whole package of characteristics does indeed describe lots of people in academia who happened to want to teach, then they’d either have to work to become better human beings, or get sort of ‘locked-in’ to being shitty, unpopular professors. Which could of course greatly impact their career upsides. *shrug*
