Getting Southerners to admit that they're wrong about anything is pretty much ASB.
Well that's just rude. That's like saying all Texans are inbred cowboys. Untrue and unjustified.
By the way LOTS of white people in the South would in fact be able to find ancestors who fought for the Union, far more than Germans who resisted the Nazis
I have family who fought on both sides. Now ask me if anyone anywhere in my family tree had slaves. The answer to that, and for most southerners, is a resounding 'no.' In those days it was STATE first, country second. I think for most of the rank and file, there wasn't inherent racism. There were simply black slaves and white free men. There's a common misrepresentation that all of the South was the way you see in relation to plantations and White Boss and Hordes of mutilated slaves. This was the smallest, wealthiest fraction of the populace.
NOT to say there wasn't endemic and multi-faceted racism. But I don't believe for an instant all southerners were visceral slavocratic automatons.
But things changed. I'd say after the defeat of the ACW, and generally the undeniable fact we are all Americans, is all that is needed to heal from the "antebellum heritage." Of course, in wording it the way it was written in the title, it makes it sound as if the entirety of Dixie is/was horrible and wrong in every facet. I don't care for that position.
There's a book "Send the Alabamians" about a troops in WW1. Their commander, stunned at their service, said, "In time of war, send me all the Alabamians you can get!" Douglas MacArthur once noted that the battlefield exploits of the Fourth Alabama had "not been surpassed in military history."
Now, call me crazy, but if Southerners as an singular entity harbored ills over the ACW, Reconstruction, and the forceful nature of eviscerating the "antebellum heritage," I don't particularly see the sort of patriotism and ardent service we can see out of Southerners throughout the 20th century.
To suggest otherwise is disrespectful and conveys a degree of contempt I don't believe I've ever taken umbrage with on this board... but then, my heritage is close to my heart, as a Southerner and an American. The two are inherently linked in my mind, and I believe in most others.
