Keep telling yourself that.
Secession was legal then and its legal now.
Not the way the South chose to pursue it. The Supreme Court ruled on that.
The form of government, a limited form of government, with power resting in the states, like Jefferson and the other Founders envisioned for this nation, not Washington DC, ended when Lincoln invaded the Southern States and brought them back into the Union at a cost of a million American dead.
Sure it did.
All because of the revenue the Southern States provided, and for no other reason.
Of course it was.
If the South had won Lincoln would have been hanged from the nearest tree, with the murdering psychopath Sherman hanging beside him.
And if flies carried shotguns then frogs wouldn't mess with them.
“The Supreme Court ruled on that”
So you agree with queer “marriage”?
