["Sociological Forum, Volume 36, Issue 3, Page 689-711, September 2021. ", "\nThe right‐wing Hindu nationalist “Hindutva” movement in India has political control of the world’s most populous democracy. To gain insight into the tools of the movement, this paper examines Hindutva framing rhetoric. Social movement framing entails the crafting of movement messages to motivate collective identity and collective action. This paper takes a new approach to studying social movement framing by using the social psychological principle of metacontrast as an organizing theoretical framework. Metacontrast involves minimizing differences within the group (intragroup homogenization) and maximizing differences between groups (intergroup polarization). We argue dual homogenizing‐polarizing frames work in concert to construct a unified collective identity and mobilize concerted collective action. Using qualitative content analysis of two Hindutva organization websites, we find Hindutva framing rhetoric simultaneously homogenizes and polarizes through two framing strategies: a threat‐counter threat frame that portrays an antagonistic outgroup that must be countered with a unified ingroup, and a striking positive‐negative intergroup contrast that paints the ingroup as a moral protector and the outgroup as a vilified adversary. Notably, key to these efforts is the minimization of deeply entrenched, rigid caste differences. Our findings have implications for the study of social movements, nationalism, collective identity, collective action, and intergroup relations.\n"]
