I’ve been seeing job ads for positions in academia that mention such requirements in the application or cover letter.
This sort of thing seems to be accepted by young leftists:
Haidt: "I have the sense that there is a large generational split. Psychologists and academics who are older than me (I'm 58) seem uniformly supportive: they are all on the left, and the left used to be creeped out by loyalty oaths, whether administered by the McCarthyite right or the Soviet left. But young people on the left seem to be very comfortable requiring such pledges."
Immediate dealbreaker; I don't waste my time applying, since I would never follow the requirements, and the college won't be hiring me anyway.
