From the 4th Lincoln Douglas debate, September 18, 1858. Lincoln said something that contradicts the view that he was a saint. In fact, he sounds like he would fit in with today's most vile gang of white supremacists. Considering what Lincoln said (below), it's not difficult to imagine how the real racists of the 1800's thought is was OK to own slaves, and that lynching was viewed as some sort of sport. Yuck.
"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, [applause]-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 forever 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."
