The purpose of this essay is to look into why women decide to join women-only feminist groups on Facebook. Specifically, we want to explore how women view their own and others’ safety in feminist Facebook groups that allow men to participate and those that do not. Another aspect of why women join separatist groups is the possibilities that surface when men are not allowed to join or partake in discussion. We took a qualitative approach to these questions of issue and interviewed eight women who are or have been members of both mixed and separatist Facebook groups focused on feminist discussion. By using a thematic analysis, we found that the women we interviewed seek separatist spaces to avoid sexism, threats and digital violence by men. In mixed groups, actions like derailing, mansplaining, threats and silencing were common and the women wanted to find women-only groups to protect themselves from this oppressive behaviour. In addition to that, we found that separatist groups often create the possibility for women to speak freely about their oppression, share private experiences and organize themselves against the patriarchal system.
