Since the Union was planning on keeping slaves in slavery, giving them votes would have simply given more votes to their masters. The idea of an Australian Ballot hadn't arrived here yet.
Stop pretending the Union wasn't planning on keeping them in slavery during the first two years of the war.
I am not going to let you take credit for something you had no intention of doing in the first place, and only did out of spite when you did finally do the right thing.
The Union was fighting for dominance, not freedom. Get the History correct.
Well... first of all, "I" didn't do any of this, though one of my great-grandfathers, non-English speaking, fresh off the boat from Europe, did serve and was wounded in the war.
Still, I would not blame him for anything you put on Lincoln, FRiend.
But to your point: in fact, the original idea for the Emancipation Proclamation came from former President John Quincy Adams when he was again in Congress, along with Representative Abraham Lincoln, in 1847.
And basically, he just revived the British Revolutionary War strategy of freeing "contraband" slaves in rebel areas.
It was a military strategy which matched perfectly with Republican abolitionist ideals, but Lincoln delayed issuing the Emancipation Proclamation until he had some sliver of Union military victory (Antietam) to make it seem realistic.
So your irrational hatreds of Union motives are simply unjustified, FRiend.
