Nothing I can imagine will ever change your mind. I'm waiting for you to claim that no Saintly Southerners really owned slaves and that it was really those evil, blood thirsty Northerners who owned all of them.
You may have missed the fact that I don't give a sh*t that Southerners (and all the Northerners before them) owned slaves.
The issue of the Civil War is whether states have a right to be free and independent of the Federal government, not whether or not liberal/progressives agree with their morality.
The slavery issue is nothing but a distraction from the actually VALID issue of the Civil War.
Northerners didn't own slaves directly....not by the mid 19th century. They sold slaves then profiteered off of the goods their labor produced. As the 3 New England Journalists who wrote Complicity put it, it was slavery the way the North liked it: "most of the profits and none of the screams."
