The Lincoln you adore is a myth.
All of your prattle trying to wrap this dispute about Constitutional powers and various historical events in “slavery” is as intellectually dishonest a thing as I’ve seen here. No one is interested in the return of slavery, and you know it.
You’re a troll.
Tau Food is far from a "troll" (whatever that word might mean), but the historical fact is that protecting slavery was the one-and-only issue which drove Deep South Fire-Eaters to declare secession, beginning after the election of Lincoln's "Black Republicans" in November 1860.
Before that, their control over all three branches of Federal Government was nearly complete, and every "normal" issue (i.e., tariffs) was considered more-or-less "politics as usual" -- certainly not cause for secession.
But Lincoln's election was a "game-changer" in their minds, because Lincoln was the first openly-anti-slavery President ever elected.
Of course, Lincoln had promised not to change slavery in states where it already existed.
But the mere fact that Lincoln wished to exclude slavery from territories which voted against it, that was enough to drive the Slave-Power into paroxysms of secessionism.
Ever since the war, and up through achilles2000 today, pro-Confederates have attempted to redefine what it was all about -- to eliminate slavery as the issue, and to find some other cause which we today might consider more noble.
So they pretend, and pretend that it wasn't all about slavery, instead it was all about "Big Government" overstepping its constitutional bounds.
And such ideas might make sense, if there was even a tiny bit of historical fact behind them.
But there's not.
Instead, pro-Confederates' beliefs are all based on propaganda lies, many of them originating from the likes of Jefferson Davis, even before his war was fully lost.
