Insurrection is not the same as secession. And nowhere in the Constitution is there a requirement for an amendment, or court proceeding for a state to withdraw from the Union.
Nor is there a place where the power of secession is returned to the states from the Articles of Confederation.
Pretending that that power had been returned doesn’t make it so.
If there was a controversy over whether the power had been returned, the states were bound to settle it in court, rather than with gunfire by Article 3 of the constitution.
By not doing so, the southern states were in rebellion, which is insurrection.
As you know, but it blows holes in your argument, so you will never be honest enough to admit it.
Instead, in the past you have lied, claiming for any state, or for the people of a single state, the general 10th amendment powers that are reserved to the states (plural) and the people.
Don’t expect you have gotten more honest. Surprise me.
