History is one thing, but how do you explain what happened now? Can you explain what is the mind-set of these Nazi and KKK activists today? Many things that have happened in the past are very evil and bad, but humankind learns as it becomes more enlightened, and we don't accept these acts of human cruelty any more. Do you think the past justifies today?  If the Confederacy had actually won the Civil War, what do you think would have happened to the black slaves who couldn't escape? What if.
