“I regard the Klan, the Anglo-Saxon clubs and White American societies, as far as the Negro is concerned, as better friends of the race than all other groups of hypocritical whites put together.”

The motive is not a desire to elevate the negro, but to humiliate and degrade those of mixed blood; not a desire to bring the negro up, but to cast the mulatto and the quadroon down by forcing him below an arbitrary and hated color line.

Context: While I was at the hotel to-day, an elderly gentleman called upon me to know whether I was really in favor of producing perfect equality between the negroes and white people. While I had not proposed to myself on this occasion to say much on that subject, yet as the question was asked me, I thought I would occupy perhaps five minutes in saying something in regard to it. 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 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. I say upon this occasion I do not perceive that because the white man is to have the superior position the negro should be denied every thing. I do not understand that because I do not want a negro woman for a slave I must necessarily want her for a wife. My understanding is that I can just let her alone. I am now in my fiftieth year, and I certainly never had a black woman for either a slave or a wife. So it seems to me quite possible for us to get along without making either slaves or wives of negroes. I will add to this that I have never seen, to my knowledge, a man, woman, or child who was in favor of producing a perfect equality, social and political, between negroes and white men... I have never had the least apprehension that I or my friends would marry negroes if there was no law to keep them from it, but as Judge Douglas and his friends seem to be in great apprehension that they might, if there were no law to keep them from it, I give him the most solemn pledge that I will to the very last stand by the law of this State, which forbids the marrying of white people with negroes.
