This paper develops an analytical framework for comparative research on political contention in the digital age and, building upon it, provides a literature review of social media research related to LGBTQ+ political contention. So far, we lack systematic insights into the literature on digitally-mediated LGBTQ+ political contention and its potential for comparative research. Applying scoping literature review, we focus on the key comparative dimensions such as political context, social media, and knowledge production. The results provide an overview of the state of the art, limitations, and opportunities while also developing an agenda for future comparative research. This paper supports the visibility of LGBTQ+ issues in a still hostile public debate for both LGBTQ+ activists and researchers. [ABSTRACT FROM AUTHOR]
