Huck Finn has been on the Leftist list for a long time. I think that novel has just faded away. I read that novel in high school but I seriously doubt it is being read anymore.

CARTMAN: Yes they are! Tom Sawyer built a raft and floated it down river with a black guy! I READ the book!
KYLE: That was "Huckleberry Finn," fatass!
CARTMAN: I'm Geddy Lee, and I'll sing whatever lyrics I want!
