The only places there that haven’t changed are the tiny game subs, to my limited willingness to use the site. I have checked the niche subs I used to moderate, and all but one is swamped with bullshit. Even that one has changed some. The only ones of those unchanged are the ones I had set to private ages before spez threw his little hissy-fit. The ones that were public are either dead, botted, or just unchecked insanity with bad moderation. Spam everywhere.
My homie, you can be an ally the same way us cishetero folks can. You just support trans folks however and whenever you can. How you choose to self label is 100% independent of that, even when that self label is no label at all.
Just don’t use the pronoun labeling at all, you’ll be fine. I don’t think I’ve run across anything where you’re required to have it. There might be, but I haven’t run across it.
Your self, your sense of identity is just as valid as anyone else’s.
