No state may secede. Are there really people who disagree? Who are they, and how slacked jawed are they? Seriously. This debate ended in 1865, and you twangy gomers really need to get past that. The only mistake made during the US Civil War was the lack of adequate justice against the traitors and the treasonous. Hundreds of thousands of traitors were guilty of high, armed treason against the US, and they weren't adequately punished. They should have been, with firing squads, gallows and gibbets swinging in the air. What a huge mistake. Only the Iraq War would match that error in its ineptitude and negative consequences.
That is absurd on its face.
The US Constitution sets the rule and the US Constitution does not prohibit succession. PERIOD.
It also does not set a wall of separation between church and state... neither does it give anyone any rights.
Lincoln simply used his executive authority to prevent succession, for the reasons he stated, which are readily available for anyone who wants to read them.
Point is that no one in the Confederacy committed treason. You're entitled to disagree, but as a sovereign nation, the Confederacy was defending its borders and citizens from foreign invasion.
The US citizen is in NO WAY obligated to defend the Government of the United States. The Government of the United States serves the citizenry, and it is comprised only of citizens, themselves possessing only the same rights which are possessed by everyone else. They have no special rights, neither are they apostles of some higher power.
The Constitution of the United States is the only bond between the citizen and the state. And serves as the singular basis upon which the citizen consents to be governed by such.
The US Government long ago departed from the gunnels of that instrumental ship, stripping itself in the process of any moral justification wherein it should expect any citizen to consent to be governed by an organism which now lives purely to sustain itself.
Only those dependent upon a government are obligated to defend it... and there are NO AMERICANS, ZERO, NOT ONE SINGLE EXAMPLE, who are dependent upon the US Government for a damned thing.
Anything gettin' through here Scamp?
