The fourth challenge we face is to unite around powerful action programs to eradicate the last vestiges of racial injustice. We will be greatly misled if we feel that the problem will work itself out. Structures of evil do not crumble by passive waiting. If history teaches anything, it is that evil is recalcitrant and determined, and never voluntarily relinquishes its hold short of an almost fanatical resistance. Evil must be attacked by a counteracting persistence, by the day-to-day assault of the battering rams of justice.
