And those men came down there with guns because the South launched a bloody rebellion in defense of their institution of slavery.
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.
The South did no such thing. Lincoln sent a war fleet that was going to attack them. Lincoln launched the war. No war fleet, no war.
Lincoln also had a plan to start the war in Pensacola, and but for the intervention of Captain Meigs, he would have succeeded in starting the war there.
