Pretending educating children on things existing is "forcing" or "brainwashing" is called hatred, by another name.

When I was 9 years old, I knew people who had black skin, that didn't "force" me to treat them differently, it normalized them to me.

When I was 5 years old, I met someone with green eyes. Did it make me hate them? Nope! It made them seem normal!

Same with gay people. Get over your bigotry.
