I've actually read Mein Kampf, twice. I dont hate Jews but I have a fascination with the nature of hatred so I went to a good source. The first time, in 9th grade, I didnt understand it. The second time, junior year of college, I only made out fairly better.

No books should be banned, you're right, people should make their own decisions. Especially since the powers that be would probably leave Mein Kampf on the shelf and burn Huckleberry Finn, 1984, and Lady Chatterley's Lover.
