I would remind you of the South prior to the Civil War.
How did that work out for the South?
They thought they had solid reason to do what they did. Some of us are rather sympathetic to some of that reasoning.
Where slavery came in, I would have to disagree, but as for states rights I think there were valid arguments.
Civil insurrection starts a snowball rolling down hill gaining size, momentum, and critical mass. Once it gets going, you can’t stop it.
I believe you avoid that type of situation.
Most of the causation of the civil war can be traced to actual shooting skirmishes in the territories and some states caused by the Dred Scot decision.
This in my view, was a major impetus to the Civil war. One wonders that if the civil war had been avoided, if what we see today with racial tensions might not exist to the degree it does.
