-caution: actual facts follow-
Hitler killed thouuuusands of Jews because he didn't like them, and people dont like to look back on him in WWII, trying to take over the world and what-not. Hitler was a brilliant leader, making truces with people like Stalin and then breaking them and invading Russia. No American wants to think about his murdering of Jews.
However, I think throwing out a perfectly good journal is a little extreme.
