I linked you to the
bathroom bills earlier, because I was talking about how awkward it would be when people who pass as men will be legally required to use women's bathrooms in jurisdictions like Texas. I don't mind talking about prisons, but it seems to me that you've just elided over the point I was making about public bathrooms.
You know full well there are people who've made enough changes to pass as male. I've met a few of them, you may well have without knowing it. Which bathroom should these people use in Texas?
Here's where some common sense really comes into play. Let's be realistic, and not get caught up in the technicalities here.
If a person successfully passes as the opposite sex, they will never encounter a problem using the restroom of their presented gender. If nobody can tell that you're female, use the male restroom. If nobody can tell that you're male, use the female restroom. If nobody can tell... then
NOBODY CAN TELL.
People who pass fairly well have never been the problem. The focus on people who pass well is a distraction, and a needless one at that.
Step back and think about what is driving this discussion, as well as these heavy-handed bills. Because they didn't used to be necessary, the entire discussion didn't used to be necessary. Trans people have existed for quite some time, albeit rare. We know they're there, and it hasn't been a problem.
Think about what situations have actually caused a problem, what scenarios have prompted people to put their foot down. Because it is absolutely NOT about people who pass - both visually and behaviorally.
The entire problem is caused by people who
do not pass. It is overwhelmingly the result of male people who do not pass as female. In fact, it is the direct result of male people who
do not pass as female,
do not behave with reasonable respect and consideration toward females... and who
demand that females must give way to their desires, regardless of the effect this has on females.
So at the end of the day, regardless of the laws in place, this is not at all about people who pass. If they pass, they pass.
I will add the caveat (which I would never have previously imagined was needed at all) that if a person who visually passes strips down and lets other people see their genitals...
they no longer pass. A male-looking person will not pass as male if people can see that they have a vulva. A female-looking person will not pass as female if people can see that they have a penis.
