While there is some merit to transgender stuff in the classroom, in the end its about driving Christianity into public schools. Teaching bible study, which if it were really taught accurately would drive it right back out of schools. Not a big fan of might makes right. I'm even open to schools individually deciding for themselves. But it wouldn't be. That's where state rights comes into play.
There's a saying someone once said: it isn't religion I fear. It's people in religion I fear.
