I don't think I can pin down a specific point where I peaked. I remember men in dresses being a thing that everyone laughed at a decade or two ago, then came this gradual shift where you couldn't make fun of that anymore, you had to accept it as truth that a man can be a woman. Whatever, didn't really bother me too much.
Then GG happened and "Brianna Wu" forces his way into the drama, and very quickly it's determined he's a troon, which just added to the humor of his stupidity. Ol' Johnny Boy was probably the first high-profile troon I learned about, but his being a man was honestly one of the less interesting aspects about him at the time, it was more fun to laugh at how utterly moronic he was.
And then more and more troons started crawling out of the woodwork, infesting spaces and making them worse for everyone while demanding that their needs be catered to. Being on the farms allowed me to watch this from a distance and have a community to discuss their insanity with, and gradually I went from my previous nonchalant stance to "fuck trannies" without really noting when the switch flipped.
Thing is, I feel like I keep getting peaked. Watching friends I'd known for years tumble down the troon slippery slope, Lucas and Dong-Gone's quest to take the farms down, the continued kowtowing of basically every institution around me to troon insanity...each time I get that utter revulsion that makes me hate troons even more. I'm far beyond the point of wanting all troons to just fuck off forever, and yet I still find ways to get repulsed by their disgusting nature.
Most recently, an AGP in my online friend group is seriously trying my patience. He literally cannot shut up about how he's totally a woman when chatting, and the delusions of how he's definitely a big tiddy anime babe run deep. Nobody's called him out on it because we've been relatively drama-free for over a decade and we like it that way, though I have noticed that pretty much everyone ignores his "teehee i'm such a soft girl uwu" schtick, so it's possible others are as annoyed by it as I am.
Regardless, I'm getting close to screaming at him that he's a disgusting creepy fetishist that needs to accept he will never be a woman, consequences be damned. I know the head of our group is anti-troon as well, so he'd have my back if others didn't like what I had to say, but the thought of doing it still makes me uncomfortable. Which is another reason to hate him, because he's the one doing something wrong, but because troons are a protected class, I'd be the monster.
