It's not the war being rehashed here. It's trying to make right the misunderstanding that blacks didn't take part in defending their land and their heritage during the civil war, and to educate us that Southern black slave owners and black property owners defended their "property" during the Civil war...and, then there is the misguided notion that Southerners were racist while northerners were not.
If you can show on this thread where that assertion has been made, then please reference it. Otherwise you and your man of straw are going to have to play elswhere.
