A friend posted on FB the list of the 100 most "challenged" books from 1990-2000. I would think that people have better things to do than challenge books. Like banning idiotic TV shows or watching what their children are doing on line or texting to their friends.
Reading involves creativity, builds vocabulary, and probably makes you more successful in life.
Leave Harry Potter, The Catcher in the Rye, and Are You There God, It's Me Margaret alone!
