Sorry but the rewriting occurs when parties claim the Traitors were right to secede and had a right to secede.
Southerners who were duped into defending the very system which was crushing them and driving them out of the South are to be pitied. Those duping them into treason are to be hated.
It was the media which made the Lost Cause appear noble to the nation through such films as Birth of a Nation and Gone With the Wind. Rare were the films defending the Union. Even tv shows abounded glorifying the Slavers' cause.
The greatest enemies the South and Southerners ever had were the Slavers who dragged the region into disgrace, defeat and desolation. They are no more representative of today's South than the Nazis are of today's Germans.
