Health brings up another great point: Judge people on their actions, not their books. When we complain of anti-Semetism it is about killings, beatings and discrimination, not about liturature. We don’t complain about Islam because of what is written. We talk about what they do.
We don’t kill people, and haven’t done so for thousands of years. Before discussing our liturature (which we already did, above) look at actions. Which European nation didn’t engage in mass murder in the last millenia, or even century?
If someone is ashamed of our heritage, who are they trying to measure it against, the Cossaks of the east or the many Crusaders of the west? How did the early colonists react when they met the Native Americans? (The first Spanish settlers — in their prime cultural moment — wrote back to their king that the Indians are so nice that it would be very easy to take them as slaves.) How did the Brits treat the Irish or all of their colonies, besides for pillaging national treasures and displaying them at home as a sign of western culture? The list goes on.
