I showed you one signed by John Adams. In the pantheon of "American gods", Adams beats the dog snot out of Lincoln, who pretty much resembles George III in this matter.
But for that matter, I believe there is a document penned by Lincoln in which he supported secession.
Any people anywhere, being inclined and having the power, have the right to rise up and shake off the existing government, and form a new one that suits them better Nor is this right confined to cases in which the whole people of an existing government may choose to exercise it. Any portion of such people that can may revolutionize and make their own of so much of the territory as they inhabit.
In 1848 Lincoln spoke the truth. After he became the Agent of New York Wealthy Interests, he spoke the will of his masters. (The same power blocks to which we are opposed today.)
You’re still trying miserably to resurrect your absurd assertion. Of course secession isn’t precluded by a union that was freely joined, but THAT is not what happened. Lincoln went against all the wishes of the founders, IMO.
But, try as you may, this still doesn’t resolve your refusal to accept a non-historical definition of civil war.
