And we've seen quite clearly what that means on the ground. By sexual conduct, they mean any sort of same-sex relationship. Moms for Liberty, the Florida group that's pushing a lot of this, works to pull the Heartstopper graphic novels from schools and public libraries. Heartstopper has zero descriptions of sexual activity beyond teenagers of the same sex (and teenagers of the opposite sex) going on dates and occasionally kissing.
And THAT is inappropriate sexual description, apparently – just because this very ordinary behavior is gay instead of straight.
