i'm a brother of SAE so i am absolutely qualified to say, a lot of my brothers/others in greek life are tribal/loveist
but it just goes with the general demographic - most students in greek life come from a higher income family, a lot are the definition of snobby rich kid, and most of this privilege doesn't also come with social awareness unfortunately (however obvious)
note i didn't click on the link so forget my opinion i guess but from the jist of it, it sounds like a social awareness class that was just given a really edgy name for the sake of stirring up the pot. i agree the name could be changed but i assume the point of the class is to theoretically 'unlearn' implicit bias that everyone is raised with
