There has been an ongoing effort since the Civil War to paint the causes of the conflict as complex. To listen to some historians, you'd think the Civil War was about everything BUT slavery. This is willful denialism in an effort to present the Confederacy, and the Southern people who almost totally supported it, in a more positive light than reality allows. The Confederacy was evil. It's main objective was to preserve slavery. Almost all southerners supported it, and by extension were on the side of evil. In this great 6 minute video a West Point History professor completely destroyed and debunks all misguided efforts in Southern apology. Let's end the moral relativism once and for all.
