Allow me to weigh in on poon vs troon as an actual TERF. None of us hate pooners for abandoning their feminity, the whole point of being gender critical is letting people color outside of the lines of gender without insisting boys are girls because they like pink. Many TERFs are butch as fuck themselves and therefore have, by all appearances, rejected societal ideas of what being a feminine woman is. So that's BS.
We used to be sympathetic to FTMs when FTMs used to be mostly very butch women or women who sought to detach themselves from the vulnerability of femaleness because some uncle or scumbag touched her in her no-no place. That all went out of the window when the Tumblr pooners showed up. Now they're just as bad as the men, only not as much of a threat because they get laughed out of gay saunas and go cry in the bathroom about it.
Modern pooners are evil in their own right, weaponizing female socialization against other women to convince them to chop off their tits and sew arm sausages on their crotch. Girls want to fit in. Girls see other smiling girls shooting up T and showing off crocheted dicks in their pants and think Hey, I want that! Whatever the "cool" thing of the day is, unfortunately these days that's tranny shit.
Troons are dangerous. They actively colonize and destroy female spaces. Pooners to some extent as well but again, they're women so they aren't forcing their way into men-only shelters and raping guys in the showers. At least I hope not. For now. Who knows with these school shooter-ass Tik Tok "non-binary" pooners.
As far as hate? Actual hate? Troons for sure. Not because I hate all men (I don't...some are quite awesome) but because every troon embodies and proudly flaunts the worst qualities of men: sexual deviance, aggression, bitterness toward women, feeling entitled to women's bodies, etc. Fuck troons, all my TERF homies hate troons. We used to be somewhat cool with them too back when they were all flaming gay dudes who just wanted to fuck straight guys and left us alone.
