Neo Confederatism is the belief that the the South was just in fighting the American Civil War. People who believe this often believe that the South broke away from the Union to preserve the rights of states and individuals. This is, of course, utter bullshit, since the explanation makes absolutely no sense, and more importantly, when states seceded and formed the Confederacy, they openly stated the reason for their actions.  Also claims of states rights falls short when you consider that the South was more then willing to use Federal power to further their own goals over the objections of other states.   If anybody wonders where this nonsense comes from, it was created by people who believed the Confederacy was just in fighting the war and then started making this shit up after the war ended to try and make the Confederacy not look as bad as it really was. They do this not only by trying to marginalize the role Slavery had in the succession in the first place but do so by referring to the war as "The War of Northern Aggression." This is of course ignoring that the South started the war by firing on Fort Sumter and even before that the supply ship Star of the West.
