From the outside, I see one giant, gaping, insane hole in the whole bathroom problem that terfs claim to have. I say claim, because I'm not convinced they genuinely think it would be a problem as much as they're just being assholes and looking for an excuse.
That hole is that they never bother to apply the same idea to trans men. If there's so much fear of trans women being predatory, why the lack of fear of trans men being forced to use women's bathrooms?
That points to it just being an excuse to be assholes.
If trans women are so dangerous because they "used to be" men, and all that testosterone and whatnot made them predators by default, then the same would have to apply to trans men.
That's why I can't buy their bullshit. Just doesn't hold up to the most basic examination as a real issue. That means it's just a thin veneer to pretend not to be bigots. So, fuck them :)
