But the OP does bring up an interesting point. I do know that as soon as General Lee surrendered to General Grant at Appomattox Courthouse and the war was over, Lincoln wanted the south to be treated as Americans, not as a conquered people of a foreign nation and he wanted to provide them with aid and rebuilt the south, even though there were some restrictions on the people of the south such as the inability to hold governmental positions and such. Honestly, I just think it depends on the viewpoint of the writers and directors of the films. Not many of them are historians and the way they portray historical events cannot be taken as factual. People of the south often still feel as though they were victims and that they were invaded by another country (being the North) and that the north destroyed their way of life, etc. It's all about perspective.
