I'll go first: in 5th grade our Catholic School librarian started reading us Harry Potter and the Sorcerer's stone. Then the Catholic church frowned on that and it was banned.

My amazing mom was luckily a public school teacher, who'd been harassed and called a communist for teaching first graders books about white kids having *gasp* friends of other races. She bought me the paperback and slipped it into my backpack to read on the bus.
(J.K. is kind of cringe these days, but what can you do?)
