The result was a Civil War, ushering the beginning of Fedgub tyranny and overreach, and the obliteration of States' Rights, sovereignty and self-determination. At what cost?
Lincoln enforced a re-joining of a broken Southern States and subservience by illegal means of coercion and the clear violation of States' sovereignty. It's lead to increasing federal tyranny and THE reason the Central Federal Gubmint eventually become just an extension of a elites' multi-National One World Government.
"Treason" and truth is in the eye of the beholder. The victors (the North) wrote the history books from their perspective. "A War Over Slavery." NOT QUITE. The South fought for States' sovereignty, NOT enforcing slavery.
States rights? States rights to own human beings. That’s the ultimate tyranny.
