Don't change the subject. I am still waiting for proof that the Constitution prohibits secession. You won't find it.
Lincoln however, BLATANTLY violated it.
You were shown. There is no reason to have it written since any such right would mean there was no constitution.
Our Founders were not such idiots that they would put a self-destruct mechanism within the document. It was meant to last forever like the perpetual Union.
States had ONE chance to legally leave and that only covered the original thirteen. ALL the other states were CREATIONS of Congress entirely. All states had almost every necessary aspect of sovereignty removed by Article I, Section 10. There was not even a right to call conventions to proclaim secession.
And even if there were such a right lurking in the penumbras there certainly was no right to attack federal property and personnel.
In what way?
