Summary: How is it that Anders Breivik, mass murderer of 69 young people could exist in a seemingly tolerant Scandinavian country like Norway? Or that anti-Semitism can be alive, well and expressed through violence in Germany and France? Or that a Sikh temple service in Wisconsin could be so violently disrupted on a quiet Sunday morning by a white supremacist with a semiautomatic handgun? What drives ethnic hatred and why do history's lessons not seem to resonate?
