RESUMO
Opposing social movements are groups that have conflicting objectives on a shared social justice issue. To maximize the probability of their movement's success, groups can strategically portray their group in a favourable manner while discrediting their opposition. One such approach involves the construction of victimization discourses. In this research, we combined topic modelling and critical discursive psychology to explore how opposing groups within the feminist movement used victimization as a lens to understand their movements in relation to transgender women. We compiled a dataset of over 40,000 tweets from 14 UK-based feminist accounts that included transgender women as women (the pro-inclusion group) and 13 accounts, that excluded transgender women (the anti-inclusion group). Our results revealed differences in how victimization was employed by the opposing movements: pro-inclusion groups drew on repertoires that created a sense of shared victimhood between cisgender women and transgender women, while anti-inclusion groups invoked a competitive victimhood repertoire. Both groups also challenged and delegitimised their oppositions' constructions of feminism and victimhood. These findings add to our understanding of the communication strategies used by opposing movements to achieve their mobilization goals.
