The South still lies about the Civil War

[JakeStarkey]

"The American South was trying to topple the American Nation and was executed for treason."

The Confederacy was as much an American nation as was the Union.
And how could the South be guilty of treason unless it was part of the same country? Can't have it both ways.

The treasonous South certainly was not legal at all. And, yes, it attacked the North, so your false dilemma fallacy just failed.
