The word "rebellion" is a deliberate lie. The assertion that they fought against an invasion force solely to protect slavery is another lie.
Slavery was not under any threat from the Union. In fact the Union practiced slavery for the entire war, so stop trying to feed us the "It was about slavery" lie.
And stop trying to feed us the "Rebellion" lie. Lincoln was not the master of the South. They were free and independent men, and one does not "rebel" unless one is subjugated by another.
As equal independent states when the nation was founded, claiming they were "rebelling", makes as much sense as saying New York was "rebelling" against Massachusetts. No, you can't rebel if you are an equal. You can only "rebel" if you are a servant.
Just one question, it’s a simple question that I think someone of even your limited intellect can answer, Why did South Carolina secede from the Union?
