The issue of Slavery is an uncomfortable one. That's why after the war the democrat argument switched to Unconstitutionality and Lincoln being an evil man ignoring the constitution. That was simply not the case. The argument or "northern aggression" is a bogus one since the South fired the first shot attacking a Federal Fort. Even General Lee said that he chose the South because of his loyalty to Virginia. At the time loyalty to one's state was a big thing.
