If I’d been raised in the South and had ancestors who fought for the Confederacy I might just share your opinion. But my great grandfather was from SE Kentucky, hard scrabble mountain Union territory in a slave holding border State where it truly was brother versus brother. The western end was Blue Grass horse country plantation Democrat and pro-Confederacy, the east was small holding Appalachia Republican. Those family traditions are mighty hard to shake, both ways.
My main beef is his acceptance/support of massive noncombatant causalties, mostly Southern, which in retrospect was a dishonorable war crime.
My family on my mother’s side was from southwest Missouri.
I had a great aunt who despised certain families in the area. I was confused about it and she told me it was because they were democrats.
It turned out the animosity went all the way back to the war. Our family were Unionists and those other families were Confederates.
I get a kick out of pro rebels on here that think nothing of slandering the Union nonstop, but blow a gasket when someone speaks ill of the confederacy.
