"Looking at what Lincoln said, he was upholding the right of revolution, not a right of secession under the US Constitution." "Any portion of such people, that can, may revolutionize, and make their own of so much of the territory as they inhabit."
This sounds Exactly like secession to me! Would you like to clarify?
At first glance secession and revolution may seem to be similar, but to the Confederate secessionists there was a big difference. A right of secession could be asserted without giving sanction to a right of revolution by the slave population. The Confederate power structure did not have great affection for the phrase “all men are created equal”.
