Do you not know the difference between voluntary colonization, which Lincoln supported, and forced deportation, which was claimed? Lincoln supported colonization, nobody is disputing that. Many people did. Robert Lee paid passage to Liberia for some of his former slaves in the 1840's or 50'. That is a far cry from rounding them up, forcing them on ships and sending them back the same way their ancestors got here. As was claimed Lincoln advocated.
There are many other examples of Lincoln's attitudes towards blacks. Although he abhorred slavery as an institution, the idea that Lincoln was some champion of equal rights is a joke.
Is it? This is from one of his 1858 debates with Stephen Douglas:
"I have no purpose to introduce political and social equality between the white and the black races. There is a physical difference between the two, which, in my judgment, will probably forever forbid their living together upon the footing of perfect equality; and inasmuch as it becomes a necessity that there must be a difference, I, as well as Judge Douglas, am in favor of the race to which I belong having the superior position. I have never said anything to the contrary, but I hold that, notwithstanding all this, there is no reason in the world why the negro is not entitled to all the natural rights enumerated in the Declaration of Independence-the right to life, liberty, and the pursuit of happiness. I hold that he is as much entitled to these as the white man. I agree with Judge Douglas he is not my equal in many respects-certainly not in color, perhaps not in moral or intellectual endowment. But in the right to eat the bread, without the leave of anybody else, which his own hand earns, he is my equal and the equal of Judge Douglas, and the equal of every living man."
I would defy you to present a quote from a single Southern leader prior to the rebellion who would go on record as saying blacks deserved any rights at all, much less place them on the same level as a white man. Two years before this, a Southern Chief Justice of the Supreme Court had ruled that a black man had no rights period and were not and could never be citizens. Two years later here's Lincoln saying they have the same basic, God-given rights as a white man. What Southerner was out there agreeing with him?
