And here I thought America was all about free speech. Coming from Aus all these books and more are required reading in school. Huckleberry Finn? We read that in yr 10. To Kill A Mockingbird? Required to read in English class in year 10. Harry Potter? Had to read and also went to see it in year 7.
Btw, I do know that these are available to read, except (some)in some schools.
