IMO you should post the videos. The context might make which case it is clearer, or at least rule out or confirm the "they are making fun of people who believe this" possibility.
The whole thing is just too absurd to do anything other than not take it seriously. Like I'm skeptical of pretty much everything you said there other than the drag queen part (though are schools hiring them or are some volunteering to do a reading thing for kids?).
Do you have any examples of that homosexual erotica in school libraries? That statement about teachers teaching kids things that have nothing to do with actual education is very broad and vague, but some examples would also be helpful, along with being more specific since that statement would include random trivia a teacher might mention for fun and parts of the curriculum that have debatable usefulness (like cursive writing), which I don't think you're talking about.
And drag queens are just men in dresses or other women's clothing. The purpose of their reading thing is for them to provide a good service for children to specifically show that they aren't evil delinquents who will predate children at any opportunity.
I wish it was that easy to protect children from predators, just picking some bad groups of others and putting a fence between them and our children. But just like a man wearing a dress or being interested in other males doesn't imply they will be interested in children, a man not wearing a dress or being interested in other males doesn't imply that they aren't interested in children.
The reality is that we need to pay attention and communicate with our kids, and most importantly educate them about sexual stuff so that they can know to tell us if something does happen to them. Don't you see that keeping them ignorant about all this stuff means that it leaves room for a groomer or molester to "educate" them? That treating homosexuality the same as actual sexual crimes when it's not a choice could mean some gay people will decide it's no big deal to predate children since they are already "doing evil" just by being gay?
