Na. Your too hard on them. It’s just an expression of that beautiful belicose rebelious American free spirit. “State’s Rights” is a nostalgic concept and the thought of a war being waged over that concept is very romantic...if you can purge the whole slavery thing from your memory and make it an unimportant or nonexistent factor.
"States Rights, which prior to 1860 had been as important a part of northern beliefs as southern, were overturned."
~ Dean Sprague, Freedom Under Lincoln, p. 300
