“Whether the American system is beyond redemption we will have to wait and see. But we can be certain that black patience has run out, and unless white America responds positively to the theory and activity of Black Power, then a bloody, protracted civil war is inevitable.”

A statement regarding the Emmett Till murder.
Paris Review interview (1958)
Context: If we Americans are to survive it will have to be because we choose and elect and defend to be first of all Americans; to present to the world one homogeneous and unbroken front, whether of white Americans or black ones or purple or blue or green. Maybe the purpose of this sorry and tragic error committed in my native Mississippi by two white adults on an afflicted Negro child is to prove to us whether or not we deserve to survive. Because if we in America have reached that point in our desperate culture when we must murder children, no matter for what reason or what color, we don’t deserve to survive, and probably won’t.

Context: Recent focus on the issue of racism has generated discourse but has had little impact on the behavior of white feminists towards black women. Often the white women who are busy publishing papers and books on "unlearning racism" remain patronizing and condescending when they relate to black women. This is not surprising given that frequently their discourse is aimed solely in the direction of a white audience and the focus solely on changing attitudes rather than addressing racism in a historical and political context. They make us the "objects" of their privileged discourse on race. As "objects," we remain unequals, inferiors. Even though they may be sincerely concerned about racism, their methodology suggests they are not yet free of the type of remain intact if they are to maintain their authoritative positions.
Context: Racist stereotypes of the strong, superhuman black woman are operative myths in the minds of many white women, allowing them to ignore the extent to which black women are likely to be victimized in this society and the role white women may play in the maintenance and perpetuation of that victimization.... By projecting onto black women a mythical power and strength, white women both promote a false image of themselves as powerless, passive victims and deflect attention away from their aggressiveness, their power, (however limited in a white supremacist, male-dominated state) their willingness to dominate and control others. These unacknowledged aspects of the social status of many white women prevent them from transcending racism and limit the scope of their understanding of women's overall social status in the United States. Privileged feminists have largely been unable to speak to, with, and for diverse groups of women because they either do not understand fully the inter-relatedness of sex, race, and focus on class and gender, they tend to dismiss race or they make a point of acknowledging that race is important and then proceed to offer an analysis in which race is not considered.
