This is a hard thread to follow, sometimes it's hard to tell what people are even disagreeing about.
The best solution is to just make all the bathrooms unisex.
Adding third bathrooms would be expensive and wouldn't solve anything.
Letting FtMs and MtFs go in the bathroom of their gender doesn't work, either, unless you live in a magical place where everyone passes perfectly. Requiring people to completely hide their physical sex is unreasonable when they just want to pee.
With unisex bathrooms, there's no outcry over seeing what looks like a man in the women's bathroom, because there is no women's bathroom. I don't see how segregated bathrooms help protect anybody at all... Sexual predators (or violent transphobes) don't care about signs. And if it's just about peeing in the same room with someone who's attracted to your gender, well... There's this common thing called "homosexuality". Segregating bathrooms does nothing about that.
So in the short term it shouldn't be illegal to use either bathroom, and in the long term they should be labelled unisex.
It's not a difficult problem... Unlike locker rooms, which are a much tougher issue. Those I understand segregating based on genitalia, for lack of a better solution.
This no quoting thing you have going is actually a good metaphor for this entire conversation. There's a standard thing that everybody else does and everybody else is comfortable with, but for reasons that are unclear you demand special treatment that is inconvenient. A few posts ago somebody pointed it out so I tried to accommodate you, but because I, accustomed to treating you like everybody else treats everybody else...neglected to accommodate your special needs, so you're getting angry at me for it.
I really wish she's make the "Please don't quote me" a hyperlink to one of the times she's explained it. I'm a bit sore over getting ganged up on after I complied and also asked why. It's a bit of a derail magnet, and making the demand without offering any explanation doesn't look so good.
