Latter-day Confederate apologists and reconstructivists post some unbelievably wrong and distorted things on the internet attempting to explain why the South was pure as the driven snow and right all along, which makes for great pointless catfights as Snugs for one can attest, but for once I have to say they actually look right compared to the Nads version of history.
They are right about one small thing. The South squawked about States' Rights while simultaneously forcing northern states to abide by fugitive slave codes. No hypocrisy involved there at all, nope, not a bit.
I may believe the South had a right to secede. I don't necessarily believe that they were right to secede.
As far as any history, I've looked at it long and hard. While I am not a trained historian, the South could not win the Civil War, defined by achieving independence and diplomatic recognition from the US, after November 1862. The Confederacy made innumerable mistakes in the Civil War, and too often failed to learn much from them.
