Limiting drag SHOWS to a certain age range seems like it would be in the state’s jurisdiction
I disagree, because there is no real difference between drag “shows” and other “shows”, other than the presence of men in flamboyant outfits that do not fit gender norms. Some drag shows may be explicit and not fit for children, but there are plenty of other shows that fit this category, and existing laws cover all of them, no matter what the participants wear (or don’t wear, as the case may be).
But there is nothing prurient with regard to a man in an evening gown reading to children at a library. All it does is normalize the fact that wearing an evening gown is an acceptable choice for a man. That’s what conservatives see as rhe real danger here: that forms of expression they see as “abnormal” are now normalized. So they make up this fiction that anything that defies gender norms is now unfit for children, no matter what the content really is.
