Well of course the people of the south have nothing to apologize for. It was their ancestors, not they, who brought on war against their neighbors and brothers.
Sorry other way around. Confederates didn’t invade, plunder, burn and rape their way through Illinois but the blue locusts did to Mississippi, much of Louisiana and anywhere else they could insert themselves in Dixie.In short if yankees had stayed in yankeedom they would have not had any problems from the new nation to their south. But the puritan/yankee habit of combining self righteous moralizing with financial greed would not tolerate having many persons escape their grasp. Thus the charter of the US to be the universal hall monitor of the planet and moralizer of the universe came to be and led us to so many interesting places and peoples, not the least our recent visit to the putative land of the Garden of Eden.
And it’s not all the ancestors. Every state in the pretend country of the confederacy had troops that served in the Union Army. They were true loyal Americans and should be honored with plaques and monuments, but for the some reason these neo-confederate losers don’t want to mention them.
