Lincoln was our first openly anti-slavery President.
He was the first to sit down with black leaders and ask them what they wanted -- return to Africa or the Caribbean?
Turns out they wanted to stay here and be treated like real citizens, so Lincoln did his best to accommodate that.
Remember, Lincoln was born in the South, and so was by far the least "white supremacist" of any Southern born president before... who... Harry Truman?
So your accusation here is false and malicious, especially since in the same breath you wish us to believe that Confederates were all just sweetness and light.
Well, let's look at Mr. Lincoln's documented words:
“I will say then that I am not, nor ever have been in favor of bringing about in any way the social and political equality of the white and black races,that I am not nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people; and I will say in addition to this that there is a physical difference between the white and black races which I believe will for ever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I as much as any other man am in favor of having the superior position assigned to the white race.”
