Bans that the only real way to enforce is subjecting children to genital inspections by the way. A lot of these bans as well from what I’ve seen take the form of “Allow parents to accuse kid of being trans,” usually in the form of “She doesn’t look girly enough,” to which the accused now basically has to prove they’re not trans. Which as stated generally has to be let an approved doctor poke at your bits until he’s satisfied you were born with the “correct” ones.
