Weren't some states instituting book bans for subjects considered "harmful"? This seems like a prime opportunity to twist some poorly written state laws and do some actual good with them.
No. States were removing books from school libraries based on content, though. I always feel a bit bitter when I research something and realize I've been misled. Book banning isn't really allowed.
While this book existing is whatever, it shouldn't be in any school. Hopefully no public libraries either.
