Have you read the Emancipation Proclamation? Far from making slavery "impossible," it was quite limited and specific. Plenty of slaves were being held after the Proclamation and even after the war. It took a constitutional amendment to abolish slavery.
Lot of that going around. But here I posted parts of Douglass's tribute because I thought that you and Pelham might be trying to imply that Douglass had no respect for Lincoln. Surely you two were not trying to imply that, were you?
