Famous quotes containing the word alliance:
“Racism as a form of skin worship, and as a sickness and a pathological anxiety for America, is so great, until the poor whites—rather than fighting for jobs or education—fight to remain pink and fight to remain white. And therefore they cannot see an alliance with people that they feel to be inherently inferior.”
—Jesse Jackson (b. 1941)
