All of those welcoming and inclusive people in kweer nerd communities will turn on you in a heartbeat the moment you make even the smallest faux pas. Nothing says welcoming and inclusive like a zealous and hyper-vigilant police state that mercilessly crushes anyone who puts a toe out of line.
It's good motivation to troon out, along with the social contagion/cult/coomer aspect of it. You can either live in fear of getting kicked out for the tiniest infraction that you didn't even know you made, or you can grow your hair out and suddenly have all the power. Also, the moment anyone points out this obvious flaw in the social system they've set up, they'll get accusations of bigotry and hatred because troons are so persecuted that no one would ever pretend to be something they're not. That is, in a community devoted to people pretending to be something they're not, where deviations from the norm are celebrated, and any hint of troon persecution will get the perpetrator summarily banished and the troon showered in attention, affection and sympathy.
One of the most disingenuous, morally bankrupt behaviours in leftist spaces but especially in a potentially anonymous forum like RPGNet is their absolute insistence that there can never be a benefit for someone to pretend to be trans. Even anonymously online in a forum that practically has in its rules a demand to regard the troon posters as more correct than anyone else, they will get angry if you even suggest that being trans has social capital in any circumstances, let alone one where absolutely no evidence is required. They do it with all idpol, of course - can't be racist towards white people, women always suffer under The Patriarchy, etc. - but places like RPGNet especially are such hugboxes for troons. They'll even act like the bigots and TERFs are secretly posting all around, ready to ban every troon poster, when anything that can be possibly twisted into a transphobic reading will get you permanently banned.
These are people suffering from severe paranoid delusions, lying about how they are treated and often even (as has recently happened
again on Something Awful) false flagging their own harassment, but you cannot question the narrative. The best you can hope for is when the troons start trying to take each other down, which is when you get someone like Dave 'Olivia' Hill banned from RPGNet not for any of his most egregious sins, but because he annoyed other trannies. From what I can gather it's not even possible to just stick to talking about games and avoid the Tangency politics side; if you're still posting on RPGNet you're complicit in treating the troons as the local high priests while hypocritically denying that they receive any benefits from their ostentatious troonery.
Tl;dr: Autistic nerds become troons and ruin the hobby they were in, many such cases. Sad. They need to be burned out at the root.
I read a lot of Manhua, and can tell you this is not too far off from what the Chinese themselves often write, so I don't know how it's a racist stereotype. This would actually be pretty tame by the standards of something like Cultivation Chat Group.
