>> The worst case I saw of this so far was an event organised by my workplace, for teaching programming. But straight white men were banned. If you were a white man you had to show photos from Facebook to prove you were gay.

Wow I never experienced anything like that.

I do find some things in popular media offensive though nowadays.

For example, I saw on Netflix there was a show called "Dear white people" and I find the title kind of racist. I'm white, I work ridiculously hard (I have no life) but at this stage in my life, I'm basically a loser (and I'm still working very hard to try to change this) so I feel hurt when other people insinuate that white people like me have it easy and don't understand real life. It's rubbing salt into the wound.

I think if there was a show called "Dear black people" or "Dear working single moms", there would rightfully be a massive backlash.
