Do they not realize that most slaveholders did not fight in the war? They stayed at home and watched young southern men die in droves. You may not believe this, I think I mentioned it once before, but my ancestors stemming from my dad's mom (who was an orphan from Atlanta) had ancestors who fought for the Confederacy. None of them owned a single slave. In fact, most of them struggled to get by. They were railroad workers, postmen, or store clerks.
Just something to think about.
True, which makes Lost Cause apologia even worse. Defending the homeland from a literal invasion is one thing, but it was those same slaveholders who led the "Redemption" and the rewriting of history around the war they instigated and then were too cowardly to fight in, letting the "crackers" die and bleed for them
(Cracker, like the term "white trash," originated with the Southern upper class)
