Don't know why that had to be a picture, but yes, and almost every state's declaration had the same point in it, usually the first paragraph.

But no, my school didn't teach that. They only acknowledged that the north had not yet absolutely banned slavery everywhere and the states seceeded before they even tried to come down hard on the insitution. They desperately want to erase the fact that the south very much had the moral low ground.

It's not too late.

Not for treason. While the union was on the right side of the slavery issue, I can't agree with the whole imperialist "you can't leave this nation, we rule you" stance. Governance should be consensual IMO, though I'm not opposed to military interventions to deal with evil shit like slavery or refusing to allow those who want out to leave (but not to enforce economic advantages).

Though ultimately it doesn't really matter and the strongest militaries, intelligence agencies, and civil obedience forces will decide in the end, as they always have.
