It seems the writer of the article and most of the posters have no clue about the civil war and see it only a fight over slavery; it was much more than that, It was about "states rights".The judgement of Lee is also off base since he believed in the emancipation of slaves.

"So far from engaging in a war to perpetuate slavery, I am rejoiced that Slavery is abolished. I believe it will be greatly for the interest of the South. So fully am I satisfied of this that I would have cheerfully lost all that I have lost by the war, and have suffered all that I have suffered to have this object attained."

Lee also wanted blacks to join into the Army and be given freedom as well as all their extended families for service

White washing history and forgetting is what totalitarian societies do. . Seems we are already there with so many willing participants  joining in ignorance. Understanding and compassion and forgiveness are the way to healing, not judgement and revenge.
