“In your mind, any American who wishes to secede from this terribly corrupt and lawless government, should be shot.”
No, any American who believes that 'the government' is 'terribly corrupt' and 'lawless' is factually wrong, and is expressing an errant opinion predicated on partisan hyperbole and fear-mongering, consequently there's no justification to 'secede.'
Moreover, it's un-Constitutional for a state to seek to 'secede' absent the consent of the other 49 states (
Texas v. White (1869)).
The United States is not a 'collection' of states, it's a single Republic with every American a citizen of that Republic, where one's state of residence is irrelevant. We are one Nation,
indivisible, and each American is a member of that same, single Nation that cannot be ended merely at the whim of a capricious, ill-informed minority.
