@7, you should look farther into what Lincoln thought about black people! Pre-war, he was a free-soiler who thought slavery was wrong but who did indeed advocate colonization abroad for American blacks. To him this seemed like an attractive solution, and stated that this was because he didn't think whites would ever be willing to get along with blacks or give blacks equality. He even met with representatives of the free black community during the war to push the idea of colonization, which they rejected as ridiculous. At the same time, he was trying to get the border states to go along with the idea of compensated emancipation, but that was rejected too.
By August 1862 he had a draft of the Emancipation Proclamation sitting in his desk drawer and seems to have been convinced that emancipation had become a military necessity - that in order to get the South back, he would have to wage total war on southern institutions including slavery, destroying the labor resources and immense property value that the slaves represented to the South. This was also intimately connected to the policy of raising black Union regiments, which Lincoln and others believed would be a total nightmare for Confederates. (It pretty much was)
Here is a letter he wrote which suggests his thinking post-Emancipation Proclamation: http://showcase.netins.net/web/creative/…
And of course, at the end of the war, just a few days before his assassination, he gave signs that he had changed his position even further. He publicly advocated suffrage for some ("the very educated" and soldiers) black men, which at the time was an extremely radical position: http://showcase.netins.net/web/creative/…
As you may know, that last speech incensed John Wilkes Booth enough to convince him Lincoln had to die. Wilkes' exact reaction: "That means n*gger citizenship. Now, by God, I'll put him through. That is the last speech he will ever make."
And it was.
I don't think that Lincoln should be declared a saint or some kind of anachronistic 19th century anti-racist. He was racist. But you do him an injustice by focusing on his colonization advocacy. There's a lot more there - and without his evolution, I don't think we would have had emancipation or the 13th Amendment.
