Nonsense and you well know it.
The truth of history is that what began as a war to defeat Confederates and restore the Union became, long before it ended, also a war to destroy slavery, first by Proclamation and finally by Constitutional amendment s.
I struck some of your filler words to get at the heart of the matter. For the purpose of this post, let's stipulate that you are correct: at some point Lincoln began to use war to violently overthrow slavery provisions of the United States Constitution.
We know before the war Lincoln did not have the necessary votes in Congress to peacefully pass a constitutional amendment ending slavery but after all the war killings, redefining states as military districts, and disbarments of voters, he did.
This is a problem for anyone who claims to support the original intent of our founders. The founders included in the constitution a peaceful amendment process, but not a provision to use the military to violently overthrow the constitution.
By any definition, consent obtained by the use of violence is not consent.
Still, many people contend the one million page Federal Register (or is it two million pages now?) authorized by the Lincoln constitution is better than anything based on “consent of the governed.”
