“You can argue that it was all rooted in evil. But they claim otherwise. ”
As I said in another comment, I have direct ancestors who fought for the Confederacy. They were supporting evil. And if you don’t get that, you really missed something in your yeshiva education. Woe to those who tried to teach you Torah!
If the racism that create the Confederate States is acceptable, so is the anti-Semitism that created Nazi Germany.
