lacrew: "Lincoln himself did not claim the war to be a war to free slaves...instead he stated it was a war to ‘preserve the union’."

Of course, Lincoln did not "start the war", Jefferson Davis did, at Fort Sumter, followed soon by a formal declaration of war on the United States.

Lincoln merely responded to Confederate aggressions by calling up the Army to suppress it.
But of course, you already know all that, right?

Protecting slavery against "Ape" Lincoln's Black Republicans was the reason for Deep South secession, and abolishing slavery became a Union preserving military strategy, which fit perfectly with Radical "Black Republican" abolitionist ideology.

And you knew all that too, didn't you?
You just can't bring your self to spit it out, right?

“No amendment shall be made to the Constitution which will authorize or give to Congress power to abolish or interfere, within any State, with the domestic institutions thereof, including that of persons held to labor or service by the laws of said State.”

This is the Corwin amendment. You should read about it and learn.
