I mean obviously a shitty thing to do and I think they've likely exaggerated bits of this due to their own personal bias of gay people being treated better, but certain institutions do have diversity standards, that if managed, help them to get public and private funding. 'Ethical' business practice is hot right now for big investors. It really throws democrat-adjacent liberals off your scent.

It also depends on the industry. My industry may be a bubble in this respect, but having a 'protected characteristic' can be advantageous in some respects. I often see jobs with schemes that openly guarantee an interview to such candidates, based off their protected characteristic alone. Of course, I can see the reasoning, and they'll still face other prejudice in the workplace, but it can be easily abused by people who are inclined to do so, especially in regards to the unprovable claim of non-heterosexuality. I've seen a lot of people make very tenuous claims to queerness (I know, I know, you can't tell someone what they are and aren't... I've HAD queer experiences and pondered my own claim to such a label) to assist in landing a job.

I'm not saying such hiring practices shouldn't be in place, although they perhaps are a liberal band aid. I just think they can be abused easily (though abuse of it is probably not commonplace)... that said given it's a Redditor I am inclined not to believe his experience of it.
