Nonsense. Regardless of whether slavery ended down south 20 years after the war, 50 years after the war or 100 years after the war that does not change the fact that the reason you claim that they had for their rebellion, "to practice the Original Principles of Government established by the Founders", would have been to the benefit of only a minority of the southerners, and would have completely excluded a third of the population.
This doesn't change the fact that the most of the "citizens" of the Northeast are now tax slaves.
I notice that you didn't address that portion of my broadside, perhaps because you couldn't. ;-)
