This paper summarizes an intensive field study of two ad hoc antipornography organizations, the campaigns they conducted, and their leaders and active participants. Data were gathered by extensive observation and document search, unstructured interviews with campaign-knowledgeable respondents, and by structured interviews with 85 leaders (Conporns), 51 opponents (Proporns), and 40 Controls. Comparative analyses of the two antipornography campaigns supported the hypothesis that the campaigns were norm-oriented social movements which could be described by Smelser's value-added stages of collective behavior. Conporns were found to be status discontents defending with a symbolic crusade the dominance and prestige of a lifestyle to which they were committed. Conporns were found, again as hypothesized, to differ from Proporns in selected demographic and social-psychological characteristics. Research problems which occurred during the course of the field study are discussed, and suggestions made for further investigations.
