Race is only one facet of human nature.
It is not like people don't do the same thing to their own race, ethnicity, gender, or religion etc.
People even do it to their family, and friends, it is just human nature.
Making Race seem any different is just not realistic. Take a look at the themes in the TV soaps, and you will see the theme.
White men are the most discriminated class, and they are discriminated by other white men, but they are not a protected class so they don't haven't any publicity or recourse.
Human nature knows no bounds.
