“It’s crazy to me that teachers aren’t allowed to pray in class,”
They’re allowed to pray. So are the kids.
None are allowed to preach.
“but they’re allowed to wave sexuality and adult topics in our children’s faces.”
The fact that gay people exist is no more an adult topic than that black people exist, or people who don’t worship the White Christ, or people who don’t eat meat. Kids will identify with one or more of those well before they’re ‘adult.’
The other option is to not say ANYTHING about sexual identities, never ever ever through school, then when the kids turn 18, “It’s all on you. Deal with it!”
