All over Europe there are memorial stones set in streets where the victims of the Holocaust once lived. These scattered memorials serve as reminders of the moral failure of the Nazis and their many sympathizers. In the USA, we have been more inclined to memorialize Confederate military leaders than to acknowledge the evils of slavery they sought to protect. The resistance to teaching a factual American history to young students about our nation’s moral failings leaves us vulnerable to making the same mistakes again. In fact, in many ways, we already are.
