It is not surpising that our current generations of politically corrected people don't know about Robert E Lee. The revisionist educators have painted him as a racist, and slammed the door of knowledge tightly shut.
One of my favorite stories about him takes place in a church after the war. A freed slave comes into a church where Lee was attending the service, the former slave went to the front of the church and knelt to say a prayer. Churchgoers were nervous, and unsure of what was going to happen until General Lee got up from his seat and went to the front of the church and knelt beside the man and said a prayer with him.
