In that, they do represent a proto-facist mind set.
Freeing two million souls from bondage was an excellent start for the new GOP.
Slavery is worse than murder? I don't know about that. Never mind many of those regimes that were murderous also had slaves in the millions.
It's not great, but frankly the fact that not everyone had to go around fearing for their very lives is telling.
There had to be some "justification" for the killing and maiming of two million, "ending slavery" happened to sound the more "noble" while the red man perished under those same guns. Funny how arrogance of moral value seems to stick us in our own backs sometimes.
How to win a war? Remove the enemy's production engine and they'll die. Slavery was the South's production engine, without doubt, no contesting that. BUT it was a Northern STRATEGIC decision to free slaves and diminish the South's ability to resist - by far moreso than it was a morally higher calling of the North to do so. The "Union" proved itself not so moral in the treatment of the red man after it's "battle of morality" inflicted on those bad slave-holding states.
