The comment I was responding to, and the particular matter I was addressing, had little to do with the 10th Amendment. Nor did I suggest the concept of states' rights as separate and important from those enumerated by the Constitution to the federal government was a concept invented by Southerners. I was quite specifically responding to the revisionist nonsense that the Civil War was a fight over states' rights, and a war of Northern aggression, as Confederate apologists today continue to like to suggest.
