People don't stop being trans because you disagree with them politically. I despise Jenner and other high profile trans grifters but I'm not shitty enough to deny their identities.
Do better. As a user of both sites this shit is genuinely upsetting. Despite how you may feel about hexbear, how can you claim that they bait people into revealing their internalized transphobia and then turn around and make shitty claims like this? I don't give a shit if you call me a tankie or red fash or whatever, but I'm trans whether you like me or not.
It really shouldn't have to come to posting estradiol every time some lemmy user tells me I'm not trans.
I can afford them but a that's not something that can be said for all trans people. We are over-represented when it comes to living outside and without social supports and as a result don't tend to have access to decent medical care. Being poor doesn't invalidate anyones trans identity.
Part of building a space we can actually participate in means building a culture of showing no quarter for questioning peoples identities like that. It doesn't matter if you disagree with them politically, it's totally unacceptable to deny them who they are.
