It’s not that simple. I am glad that the rebels won independence from England, and I am glad we abolished slavery. The rebels were born English, but you are determined not to admit it. Very few CSA troops owned slaves.
The rebels were born as Americans, subjected to a Crown. I’m well aware not all Southerners owned slaves. They were used as tools by an elite, land owning and slave holding class.
And tell me, if the South had won the war what would have become of the slaves? Would they have been set free?
