Considering almost all of my interactions with trans people come from neogoof, Reeeeesetera and himu/Cindy, I'd say the prevalence of serious mental health problems and trans people are pretty fucking high and some hardcore therapy might just be necessary before allowing them to make life altering decisions, especially if they're teenagers.
Actually, Himu wasn't too bad during his phase, especially when you account for him being Himu in the first place. I certainly don't remember him doing any of this performative bullshit of trying to act like the most oppressed class on Earth nor demanding that everyone else has a duty to affirm his beliefs. Again, accounting for that he's Himu.
There were less insane trans people on ResetERA.com too. They've ran off or banned the more sane members for crossing the cult, some of them have converted to the cult, etc. There were shit stirrers but I really don't think the KitKat/Robin/SweetNicole regime was necessarily worse than the current one. They started a lot of this shit, it was SweetNicole who began the STAFF POST imposing an opinion on threads and then banning anyone who dissented after all, they mobbed up to hang Royalan, they let incelsiorlef jump on "truscum" and run them off, etc. But actually now I've talked myself out of pretending that era was any better.
I'm not going to pretend that NeoGAF.com had less insane members or less insane trans members, HUELEN (PBUH) claimed to be trans after all, but I know of at least once trans member (now long gone) who told me they appreciated my stands for free speech and for dissent and NeoGAF.com was probably not clearly worse than ResetERA.com is about those things. There's probably members of ResetERA.com who feel the same way, maybe even trans members, but I doubt they could say it publicly. (I know people didn't feel that way on NeoGAF.com, this person did PM of course rather than ever post it.)
Trans people I've known in the real world aren't any different than anyone else but I read a post a while ago that did make me think a little, and some of the other responses you got approached this, that I don't know what those people do online. They might be totally fine in the real world then go online to post lewds on Twitter in between screaming at Joanne to die in a grease fire. Do you think incelsiorlef's coworkers at the grocery store know how insane she is? Yeah, they know she cries to get out of work so she can browse Twitter but they probably don't see her ResetERA.com posts. She probably comes off as a jerk rather than a complete loon who may be a member of a cult.
I've mentioned before my main beef is about "trans" kids, as I said in Himu's thread I think there should be
less gatekeeping for adults, but since I also oppose the totalitarian nature of the cult I'm sure that despite that middle position and my openness on the first position if there were good arguments for it I'm going to get the same treatment that Joanne and marrec and trans women like Erica Anderson get. If Joanne can publicly support everything about gender identity, proclaim "trans rights are human rights" and all the rest but then the cult is going to lie about her, saying she wants trans people exterminated, that she funds trans genocide and works with Putin while demanding her fictional works be erased from history then I'm not particularly interested in aligning with people who do this. I will always defend their actual rights and oppose their actual persecution, as I do for all individuals, but I'm definitely not going to follow their lead, grant them extensive leeway and support their demands for a duty on others to affirm their beliefs at all times. They're mostly harmless, yes, but what they advocate for is not. If arguing against the latter makes me a TERF and "denies their right to exist" then I just have to accept that I suppose. (Which, I think was also Dave Chappelle's argument. So great, another white comedian I'm apparently siding with in the Great Comedy Race War.)
