While the contentious politics (CP) model has come to dominate the field of social movements, scholars note the paradigm's shortcomings, especially its narrow focus on movement organizations, public protest, and political action. The conceptual wall between lifestyles and social movements has created a theoretical blind spot at the intersection of private action and movement participation, personal and social change, and personal and collective identity. We suggest that lifestyle movements (LMs) consciously and actively promote a lifestyle, or way of life, as a primary means to foster social change. Drawing upon our observations of a variety of LMs, we discuss three defining aspects of LMs: lifestyle choices as tactics of social change, the central role of personal identity work, and the diffuse structure of LMs. We also explore the links between LMs and social movements, CP, and conventional politics. Finally, we demonstrate that LM, as a new conceptual category, is applicable across a range of movement activities.
