Introduces and explores new religious movements, sectarian spin-offs, and alternative communities in the U.S. that have tested the parameters of acceptable "religion" at different moments in history. Particular attention is given to intersectional dynamics. The class questions the politics and practices of labeling, especially the language of "cults," and centers on specific historical case studies in order to illustrate and analyze major theoretical and methodological challenges in and for the study of religion(s). It considers what draws people to create and join new religious movements, the distinctive worlds such groups endeavor to build, and the controversies that have historically attended them.
