“I dislike it when instead of saying Jew they say Hebrew or Israelite, or Semite, I do not like it and why should a Negro want to be called colored. Why should we want to lose being a Negro… I have stated that a noun to me is a stupid thing, if you know a thing and its name why bother about it but you have to know its name to talk about it. Well its name is Negro if it is a Negro and Jew if it is a Jew and both of them are nice strong names and so let us keep them.”

I imagine that in his ancestral line, one Israelite woman married a white man. Still, he's an Israelite.

Context: I agree with Ralph Ellison when he asked, perhaps rhetorically, why is it that so many of those who would tell us the meaning of Negro, of Negro life, never bothered to learn how varied it really is. That is particularly true of many whites who have elevated condescension to an art form by advancing a monolithic view of blacks in much the same way that the mythic, disgusting image of the lazy, dumb black was advanced by open, rather than disguised, bigots.

Fourth Lincoln-Douglas Debate (Charleston, 18 September 1858)
1850s, Lincoln–Douglas debates (1858)
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.
