Why didn't anyone challenge Derek when he became a racist?

Rating: 9/10 (12 April 2006)

My 9/10 rating is because "American History X" is very well done in every way, except that it seems that when Derek Vinyard (Edward Norton) started spouting out the anti-Semitic diatribe, they should have asked him what became of his humanity. Then again, maybe they wouldn't know what to say in such a situation.
But other than that, the movie is quite good. Portraying a reformed Derek trying to prevent his younger brother Danny (Edward Furlong) from becoming a white supremacist, we get to see various issues. For example, when Derek is in jail and gets to know a black man for the first time, his anger starts to ebb. Good support from Beverly D'Angelo, Elliott Gould, Stacy Keach and Fairuza Balk make this a very good movie, even if they didn't develop it as far as they could.
