Well maybe it's not that extreme. But I took that Harvard IAT Test, which reveals hidden biases that we might have. My results showed that I have a "moderate automatic preference for 'Whites' over 'Blacks'." Take the test, see how prejudice you are and don't know it yet.

(note: there are 14 tests. I took the religion test too. I favor 'Judaism' over 'other religions.' Go figure. Prob cause I think Christians are brain-dead.)
