I think mankind's biggest mistake was separating men from women when it comes to pissing and shitting. It would much more economical to have gender neutral bathrooms, lined with cubicles, along with another separate urinal room for those with cocks.

Also, you misinterpret the point I'm making in this article. Unless you're having sex with them or treating them as a general practitioner, you don't need to know what package they have between their legs.

Based on your argument, that would mean I, as a gay man, should not be allowed in the men's bathroom because I might perv on other men. Should all lesbians be allowed in the men's bathroom instead because they're not attracted to us? And what about bisexuals and pansexuals?

Trans women and trans men need to pee, just like the rest of us. Does it really matter where they do it?

As I state, if women have a problem with predatory men pretending to be women so they can perv on them in bathrooms, then their problem is with predatory men. Not trans women.
