What I got out of it is that the author is a lying douche who makes up bullshit to fit his preconceptions. Distorting history in one way is not a solution for solving it another way.
I fully agree. “Making shit up” to challenge it isn’t a good response. The real Confederacy was not Teh Ultimates Ebillz!, nor Hitlers grandaddy. It was what is was, good and evil alike, and we do ourselves and our children a gross disservice when we pretend otherwise.
