[Age of Reason]

A state could legally secede ONLY if an amendment were to be passed allowing it.

Does it say that in the constitution?

Since the Articles of Confederation stated repeatedly that the Union was to be "perpetual" and the constitution was to "make a more perfect Union" logic requires that it be perpetual also since a less than perpetual Union was be less perfect than a perpetual one. I realize logic is not the Defenders of the Slaverocracy's long suit but there it is. The constitution is meaningless with a right of states to withdraw unilaterally.

However, Madison's remarks regarding another of the D.S.'s favorite arguments, a conditional ratification of the constitution with a right to withdraw, are most telling since he is considered the "father of the constitution." Check out his letter to Hamilton during the NY state ratification convention when Hamilton was about ready to buckle and allow the convention to ratify with the condition it could withdraw at will. Madison said that ratification was not revokable and joining the Union removed any "right" to secede. Argue with him.

Yes, it does it states that the constitution can only be changed by the amendment mechanism not by individual states.

Certainly any state that ratified the constitution could not change that ratification. Other states were admitted to the Union by adhering to and adopting the constitution.

Any state law withdrawing from the Union was automatically unconstitution.
