Don't want to hijack that airplane thread, so I'll start this one.
I'll take the opposing view.
Let me state right up front that I abhor slavery and believe the "South" was incredibly wrong and blind to the injustice created by the "peculiar institution". I'm glad it ended and wish they'd have voluntarily given it up much earlier.
OTOH, I think the Confederate Generals, many of them West Point grads, were overall a very intelligent group, schooled in the Constitution and the relationship of the Army to the government and the Constitution.
I've never been able to find anything in the Contstitution or Bill of Rights or other such documents up to the point of the Civil War that prohibited any State from removing itself from the Union. I've found nothing to that effect in the writings of the Founding Fathers, either.
Therefore, I am somewhat comfortable with the idea that the position of the Confederate Generals and indeed of the political leaders of the South were more astute scholars of the Constitution than Lincoln was. They, in my opinion, were Constitutionally correct in saying they could remove their States from the Union.
Remember too, that "ending slavery" was not a Northern War aim when it all started. The causus belli was "to preserve the Union", a Constitutionally unsupported aim, IMO.
Additionally, there's that pesky 2nd Amendment which meant to allow the people or states to remove themselves from a government that violates the Constitution or behaves in a tyrannical manner. The writings of the Founders support this view, I believe, quite clearly.
Of the two sides, it seems clear to me that Lincoln either had the least understanding of the Constitution or chose to ignore it.
He violated the civil rights of US citizens through conscription, suspended the writ of habeus corpus, and instituted an income tax which clearly was not allowed at that time and is in dispute even now. In the case of Ex Parte Merryman (1861), Lincoln not only ignored the Supreme Court’s ruling, he then wrote out a standing order for the arrest of Chief Justice Taney. Not exactly a Constitutional Champion, eh?
So, can I admire the Confederate Generals? Actually, yes, given that ending slavery was not a Northern War Aim until things were going so badly for the North that Lincoln tried it to put pressure on the South. The Confederates were more clearly Constitutionally correct. IMO.
There's another issue to be considered as cause of the war from which the Southern "states rights" grows. Before his election, Lincoln had promoted very high tariffs on foreign imports, using the receipts to build railroads, canals, roads, and other federal pork-barrel projects.
The tariffs protected Northern manufacturers from foreign competition, and were paid mostly by the non-manufacturing South, while most of the proposed "pork projects" were to be built in the North. Thus the South was being forced to subsidize Northern corporate welfare.
Not suprising they wanted to pull out of that sort of deal, is it?
