Try a little economics before making such a dumb statement. Slavery at the time was becoming extinct because of economic reasons. It was easier to turn former slaves into sharecroppers and a lot more productive in the farming south.
Other country's in the American continents had ended slavery peacefully because it was inefficient and not because they were non racists. Those that did had intergrated former slaves into their society much quicker than it took the US after it's destructive civil war.
Finally, Lincoln suggested an amendment to the Constitution, which would have been the 13th, to legalize slavery throughout the south in order to stop secession which was the right of all states at the time.
