  Despite decades of anti-caste efforts, sociocultural practices that
marginalize lower-caste groups in India remain resilient and have even
proliferated with the use of social media. This paper examines how groups
engaged in caste-based discrimination leverage platform affordances of the
social media site X (formerly Twitter) to circulate and reinforce caste
ideologies. Our analysis builds upon previous HCI conceptualizations of online
harms and safety to inform how to address caste-based othering. We offer
theoretical and methodological suggestions for critical HCI research focused on
studying the mechanisms of power along other social categories.
