No, this issue is dumber than that. Most of the problem books are in schools because of teachers not realizing that an illustrated book can contain adult content. This Book is Gay talks about best practices for using Grindr, Gender Queer was written for and advertised to adults and the author never intended it for children, but both of those books have lots of pictures so they ended up in school libraries.
It's not hard to imagine what happened here with good intentions. Even the switch of Anne Frank's perspective on prostitutes, the author was probably thinking they wanted to represent the whole of her diary because that was their vision of Anne Frank, but be a little more sex positive about it because that's their views on sex. I'm sure it's the personal expression of the author, and not a conspiracy to groom kids. And then the schools see the Anne Frank graphic novel and assume it's perfect for their classroom probably without reading a single page. (I obviously disagree with an author who has personal views that lead to sexing up Anne Frank, but I don't think it's a plot to groom kids.)
The only wrong thing being done on purpose is after it's found that inappropriate content made it into schools, after parents say "hey, I don't want my kid finding this in the school library", when the culture war kicks in and demands those books be available to all children and anyone who disagrees is a book burning Nazi. Which is a shame, since those people have such a loud megaphone, many people only hear about book burning Nazis and don't realize there's genuinely objectionable content in schools. If you ask people if the book Gender Queer with a vague synopsis is appropriate for schools, you find a slim majority support it. If you show people the content, it's nearly unanimous opposition, even among lefties and liberals.
It is possible to have conflict and disagreement with good intentions on both sides, but that gets neither clicks nor votes, so any attempt to desexualize schools is going to get mega headlines in the left-leaning media.
