This article offers a critique of the common notion in contemporary anthropology that a positive attitude toward the people under study is a necessary precondition for a sophisticated understanding of their social world. The empirical sociology of religion that evolved during the last decades of the Soviet Union's existence started from the premise that religion was a harmful phenomenon slated for disappearance. Nonetheless, atheist sociologists produced increasingly complex accounts of religious life in modern socialist societies. Their ideological framework simultaneously constrained Soviet scholars and forced them to pay closer attention to religious phenomena that contradicted political expectations. Drawing on this extreme example of militant atheist scholarship, I argue that studying 'repugnant cultural others' always requires some form of affective motivation. Antagonism can be as powerful, and as problematic, a motivating force as empathetic suspension of judgment.
