Hah! You think they actually put in place the infrastructure needed to support this asinine policy. If there aren't enough people to get the affidavits signed then those kids can't go expose themselves to dangerous ideas, presumably including "trans people exist" and "slavery was bad, actually".

See also voter ID laws that just happen to come into effect as the DMV offices in poor and/or black neighborhoods close down. If they make it a sufficient pain in the ass they don't have to take the legal or political flak for outright banning it.
