Fine. Don't worry, I'll make it short.
African-Americans suffered through centuries of slavery in this country followed by a century of Jim Crow discrimination. Though most of that has vanished since the civil rights movement, the legacy of it remains- in the utter poverty of so many black people, the disintegration of family life, poor education, crime, etc. If as a result of all this, a certain number of blacks see racism even when it doesn't exist, or when an even smaller number express racism themselves, it should come as no surprise to anyone. It's also of very little significance.
While certain white groups, mostly immigrants, have faced some discrimination in the past, it was never equal to the black experience, nor were they discriminated against for being white. Certainly anyone growing up white in this country has no institutionalized memory of racism, no fear of being stopped by police because of their skin color, and, statistically, face much better odds of a good education, a better standard of living, and economic success. So when I hear white conservatives complain about discrimination and a "double standard", I think it's pathetic.
Your turn.
