There's a difference between banning things (including books) for use in schools and the federal government declaring certain books illegal. We are dealing mostly with the former here. California doesn't want its schools reading Huck Finn and To Kill a Mocking Bird, Florida doesn't want its schools reading Gender Queer. Anyway, that's all mostly a red herring. There's nothing stopping kids in either state from going to a public library to check them out and read them.
