"The organizers first job is to create the issues or problems, and organizations must be based on many issues. The organizer must first rub raw the resentments of the people of the community; fan the latent hostilities of many of the people to the point of overt expression. He must search out controversy and issues, rather than avoid them, for unless there is controversy people are not concerned enough to act. . . . An organizer must stir up dissatisfaction and discontent."
