I would also hate if a school wasn't allowed to talk about the holocaust because a german student's dad felt oppressed, and I also hate that the southern states seem to be hell bent on continuing to spread propaganda about the civil war to keep the lost cause myth alive.
Just because a parent THINKS "being gay" is sexually suggestive doesn't mean that it IS. The world is full of black people, trans people, women, gay people, weird people, dumb people, straight people, sad people etc, and it is morally reprehensible to not teach kids to respect them as fellow human beings just to please someone who has a closed mind. Some day little timmy might have to go to work with someone who doesn't fit into your tight knit idea of what a normal person is, and we shouldn't saddle timmy with your poor opinions about who deserves the pursuit of happiness. You either think every human deserves a basic amount of respect and dignity or you don't.
We literally had to go to court in this country just to teach kids that evolution is a thing. This is just more of the same.
