How are you going to manage those occasions when there are or aren't feminine issues, intimidation, a requirement for privacy individually, and how will you know when or if they should or should not be applied?
Seems to me you are creating something that will be a nightmare to deal with, and imposing that something on 99.6% of the population for the benefit of 0.4% of the population. Not acceptable IMV.
{ETA: You keep saying imposing something on 99.6% of the population for the benefit of 0.4% of the population. First off, the men at 49% of the population are not affected at all. Of the 51% that are women, they don't run across that 0.4% hardly ever, and when they do, it's no different than when they run across any other member of the population. Nothing is being imposed that we all haven't been dealing with for years, except that some people want to treat tranny freaks like ◊◊◊◊ with legal.backing}
Honestly: when we say "transwoman", I think of the only one I know personally and the couple I've seen around. They are totally normal people, males who for all the world look and act like women. I don't think of them as freaky pervs. They're just some other people to me, like all the other people I come across. The only difference is they got a wire crossed up there somewhere.
I totally get the arguments you and others have put up (and they are very very different). I actually respect them all. But respecting someone's concerns doesn't mean they are the best choice in net.
Transpeople are less than half a percent of the population. The pervs are an even smaller percentage of them. There should be a way to make everyone reasonably comfortable here without flying off to the extremes.
On your side, women are put high on a pedestal. Despite my Southern chivalry, I look at women as my dead equals (as long as it isn't a physical contest), and what I put up with (like a transperson or natal woman in the men's room), I intuitively feel like women are strong and tough enough to handle without breaking a sweat. Hell, I'd expect that they might be less misogynistic and sexist than most men. It's not my perspective that they are the weaker sex and need to be protected from a man in a non combative situation. My mom, my wife, my daughters and my female acquaintances are forces to be reckoned with and will stare down anyone that thought they would intimidate them.
But as Emily's Cat says, sometimes it is a physical threat. What does the data tell us? It doesn't really happen. The pervs are perving with or without selfID access, and IRL we see that instances of creepiness and violence don't increase. That's something to consider, despite its counterintuitiveness.
