@LeapingLlama and @Winewinewinegin the thing is, until very recently, transwomen were welcomed into women's spaces. I've been in LGBT+ circles my whole life, and until the last few years, if someone came out to me as trans, or I met someone as trans, my baseline feeling was a warm fuzzy one of political and cultural sibling-hood. They were in the same boat as me, all gender nonconforming people together, and it was a good feeling.
The Shons of this world have overturned all that. TIMs like Shon don't want to just live quietly presenting however the hell they like, just like the rest of us. TIMs like Shon want to subjugate women. I don't know why - maybe they hate us, maybe they are insecure, I don't know. At this point I don't even know if their reasons make any difference, as we are just too busy trying to hang onto our rights to sit down and worry why these misogynistic males hate us so much.
And of course the old-school transsexuals, who everybody (both they themselves and women) knew were male, but were accepted into women's spaces with a nod and a wink - well, that's all gone now, that acceptance. When you have a hundred wolves at your door it's impossible to spot the one wolf that doesn't want to rip you apart and let him in.
