Well, an argument of moral superiority of the North under Abraham Lincoln also rings untrue.
Lincoln's Emancipation Proclamation in 1863 (as I believe both me and Pariah have already cited here earlier, in both this and similar topics here) freed only slaves in Southern States, and did not during the war free slaves in the North belonging to Lincoln's political allies.
Lincoln said in a letter that if he could save the Union by freeing no slaves, he would do that. If he could save the Union freeing some of the slaves, he would do that. If he could save the Union by freeing all the slaves, he would do that. The moral superiority of the North, and the ideological purity of Lincoln freeing the slaves, is revisionist history, and not the true situation. The North were not the pure good guys, and the South was not pure racist evil. On both sides, while racism was in the mix, decisions were made more for reasons of economics and political viability.
