Not myself, but once my daughter came home from school where she had been studying about the Jewish holocaust, the African slave trade, the Japanese detainment camps during World War II, the segregation laws, etc., and said, "Mom, I'm ashamed to be white."

I told her she didn't have anything to be ashamed of, because she didn't do any of those things. Then further research of our family tree revealed that we are descended from a murdered Native American chief on one side, and a prominent abolitionist on the other. Nobody in our lineage has ever owned a slave or participated in an act of genocide, and in fact our ancestors were fighting those crimes. So we don't need to feel shame at all.
