I was referring specifically to the Nazis making Jews wear a Star of David armband. Point is that making a minority subgroup of a population (transgender in this case) have to wear a badge just to go to the bathroom is going nowhere good.
Well the Handicapped need to carry proof that they are indeed handicapped.
That is the co-relation I would draw upon. Though it is mostly because the handicapped get special privileges rather than they need ID just to use basic ones everyone else have.
Still this issue won't resolve itself anytime soon.
Since it relies on what you consider someone's sex to be and whether or not bathrooms are gender or sex specific.
Which for a conservative state, a bible belt state, and one with a significant old population... it doesn't look good.
I do wonder how you could resolve it though.
EDIT: I just realized something, wouldn't laws like those in Texas, Florida, and Kansas violate the federal (and perhaps state) anti-discrimination laws? Because I can see a collision between those happening.
It definitely could be challenged on those lines.
Most likely the defense that it isn't "discrimination" is that TECHNICALLY everyone falls under that law. Even as a male you have to be able to prove you are indeed a man.
