As I have repeatedly pointed out to you, the Southern reasons for seeking independence are irrelevant to Northern reasons for invading the South.
Since only the reasons for invading matter, the cause of the war clearly hinges on those. Had the North chosen to stay in it's own states, there would have been no war.
The reasons they decided to go South, are the cause of the war.
Complete nonsense. Freeing the slaves in areas in rebellion was well within Lincoln's powers as granted by the Confiscation Acts.
Confiscation Acts cannot repeal Article IV, Section 2. People keep lying to themselves when they claim that something specifically forbidden by the Constitution can be overridden by a vote of Congress.
It cannot. Honest people will recognize this was a case of refusing to follow constitutional law because they didn't like that particular law.
But completely relevant to the South's reason for starting the war.

The Supreme Court disagreed with your somewhat eccentric analysis of the Constitution and Article IV.
Honest people will recognize this was a case of refusing to follow constitutional law because they didn't like that particular law.
Or more accurately, a case of refusing to accept a Supreme Court decision as valid because you don't like it.
