Here's a little something to chew on.
In this scenario, we're expected to believe that sexual predators are going to dress up as women to gain access to the ladies room and wreck havoc on our daughters. This has never really happened, but let's go along with that logic for a moment.
So this hypothetical pervert, under current law that protects transgender people, dresses up like a woman and gets into the ladies room and spies on women. Okay. So to prevent this, we're going to make transgender people use the restroom of the gender they were assigned at birth, regardless of their appearance and current status.
Now stay with me.
Trans men (people who were female at birth and have transitioned to male) would be forced to use the ladies room under these laws. Trans men look like men. A lot of them have beards. You would not know most of them were once female. But ever time they use the restroom, they're going to have to deal with the fact they they look like men, and probably have to explain themselves. These men would suddenly have a visibility that they didn't have before, and you'd probably be surprised by how many of them are about. But women would just have to get used to it, because it's now the law. But what you've done is normalize the sight of men in the ladies room...
So, now the 'sexual predators' don't even have to dress up. All they have to do is claim to be trans men. Think about this really hard.
Now, these predators can walk right into the ladies room, give some bullshit line about "yeah it's really awful that I have to use this restroom now" and spy on women with impunity.
So, geniuses, you've just made it a whole lot easier for sexual predators to gain access to women's spaces.
