(Edit: only one page is from Gender Queer, another is from a different book that was removed.)
If a parent wanted to give this book to their child at an appropriate age, that'd be fine, but just hanging out on a shelf at primary schools with very young kids seems like too much.
I really wish schools would focus on the basics: reading, mathematics, writing. There are too many educators that are trying to mold them into indoctrination facilities for politics and new theories of identity. There is plenty of time to do that at university.
