Quiet activism as feminist practice
Feminist Anthropology, EarlyView.Abstract In this article, we discuss how women combat silencing in the face of violence and increased political turmoil through quiet activism in their day‐to‐day lives. Centering lengthy conversations with Arab women across London and notes from an ongoing collaboration with a feminist activist based in the US, we examine how wearable rhetorical ...
