Yeah, not completely new, but with the rise of LLMs, a new riff on an old stereotype.
It's amazing how some simple questions about what gender means can get someone to show their whole ass.
Except that I've seen the same exact shit in irl orgs, pushing out marginalized comrades. Just because this is the internet, doesn't mean you're exempt from examining your privledge and holding solidarity with marginalized people by shutting the fuck up and listening.
I'm so tired of leftist spaces that go hard on trans liberation, but are happy to throw other minorities under the bus.
Full disclosure, I'm white, so I don't have any direct experience with racism, but I am trans, disabled, and poor, so I do have some experience with oppression. That said, fuck people who demand oppressed people always remain civil and never express anything negative, lest their precious oppresser fee-fees get hurt. We're allowed to be fucking angry and tired of shit. We should be allowed to fucking vent without worrying about "allies" getting pissy. Solidarity comes from the top down. It needs to be unconditional. And it shouldn't depend on the oppressed being nice to their oppressors.
Sending you lots of love and solidarity, comrade. 
Oh hey, I'm in that screenshot!
Here is a great source that I think will answer all your questions. :)
stay classist, 
Also, in a lot of cases, the people you're educating aren't the people you're arguing with, they're the people watching the conversation unfold. I've personally learned an incredible amount just from lurking and seeing leftists pushing back on lib takes.
Was talking to someone on Lex (queer social/dating app), got ghosted after info dumping a tiny bit, then they made a post saying everyone they talk to sounds like an AI.
