Here's a solution....
How about trans folks use the bathroom where they were using it before conservatives needed another manufactured culture war battle to fight??
Or do these folks think trans folks just started using the bathroom a couple of years ago?
Well, in the 80s when I was in high school, it was unheard of kids coming out as trans while minors in school. So this would be before the "manufactured culture war". Girls used the girls restroom, boys used the boys restroom. If a kid known to be a boy decided to just start using the girls restroom, there would be hell to pay. Same for a girl that decides to use the boys restroom.
