I love this year's slogan: "Think for yourself and let others do the same." I think this really gets to the heart of the issue - people have the right to read whatever they want (and to monitor their own children's reading habits), but they do NOT have the right to tell anyone else what they can and cannot read. It becomes censorship when people start challenging other people's right to read or trying to ban books so that no one can read them.
Here's a list of the 10 most challenged books of 2009.
How many of them have you read? I've read To Kill a Mockingbird (which is my all-time favorite book!), the Twilight series, The Catcher in the Rye, My Sister's Keeper (which is by one of my favorite authors), and The Chocolate War.
