Ironically I just finished watching this 2 minutes before I saw this thread!
If anything the movie doesn't touch on any reasons why racism is bad besides "hate begets hate."
If anything this film makes a case for racism because the facts that are brought up about "border jumpers" and the crime rates of negros, etc are indeed the facts.
I loved the part where the jew teacher makes the comment that the jews have been persecuted for 5000 years. Look at where jews are now? They completely control major industires like entertrainment, law, banking and of course anything involving finance.

.
Interesting points to make in a movie trying to say that negros got it bad due to cultural bias.
But, the movie never touches on the fact that racism is fundamentally evil because it prejudges someone's value based upon meaningless outward appearances. People can only be judged individually because thats what everyone is (black or white or whatever). Racism is merely the focus on race - which is of course just another horrible collectivist concept.
So, due to that complete disregard for the real issue. Its a thumbs DOWN.
