The only title I recognize is The Bluest Eye by Toni Morrison [I haven’t read it].
Most common reason seems to be sexually explicit, frequently with LGBTQIA+ content.
I recognize some of them. Many of them are YA novels.
I’ve only read The Bluest Eye, but have heard of a bunch of them. (did see the dying girl movie though)
LGBTQ content is the primary reason, but a close second is discussion of race.
On behalf of To Kill a Mockingbird and Adventures of Huckleberry Finn, I protest.
Almost all of them are young adult novels, and of recent publication.
Not surprising that people don’t even recognize them – that’s pretty far from the average demographic of dopers here!
It makes sense that they’re mostly YA books. The censorship battle in the US is mostly fought in school libraries.
