“In the struggle for human rights and justice, Negros will make a mistake if they become bitter and indulge in hate campaigns.”

1950s, Give Us the Ballot (1957)
Context: This is no day for the rabble-rouser, whether he be Negro or white. We must realize that we are grappling with the most weighty social problem of this nation, and in grappling with such a complex problem there is no place for misguided emotionalism. We must work passionately and unrelentingly for the goal of freedom, but we must be sure that our hands are clean in the struggle. We must never struggle with falsehood, hate, or malice. We must never become bitter. I know how we feel sometime. There is the danger that those of us who have been forced so long to stand amid the tragic midnight of oppression—those of us who have been trampled over, those of us who have been kicked about—there is the danger that we will become bitter. But if we will become bitter and indulge in hate campaigns, the new order which is emerging will be nothing but a duplication of the old order.

Context: You’ve got to look at life clearly. No rose-colored glasses. The human race is not very admirable. It was a big mistake of God’s... The more I see of people, the more bitter I become. I think I appeal to readers because there’s nothing false or hypocritical in what I write. And they recognize themselves, and recognize their fears. And they know what bastards they are.

Manifesto of Montecristi (1895)

1860s, Speech at Hartford (1860)
Context: The proposition that there is a struggle between the white man and the negro contains a falsehood. There is no struggle. If there was, I should be for the white man. If two men are adrift at sea on a plank which will bear up but one, the law justifies either in pushing the other off. I never had to struggle to keep a negro from enslaving me, nor did a negro ever have to fight to keep me from enslaving him. They say, between the crocodile and the negro they go for the negro. The logical proportion is therefore; as a white man is to a negro, so is a negro to a crocodile; or, as the negro may treat the crocodile, so the white man may treat the negro. The 'don't care' policy leads just as surely to nationalizing slavery as Jeff Davis himself, but the doctrine is more dangerous because more insidious.
