This volume proposes “speaking up” and “talking back” as new theoretical access points for studying feminist activism in digital spaces. Drawing on the influential work of bell hooks, it highlights social justice interventions by feminist/queer/decolonial actors, groups, and collectives who recover the digital as a space for activist organizing and campaigning. In presenting a variety of sociocultural issues, such as gender violence, queer discrimination, or migrant hostility, the book centers empowerment practices in their digital forms, showcasing interventions in Asia, Europe and the Americas — thereby critically examining the conditions for marginalized voices to speak up, talk back, and be heard in digital publics. In focusing on activist practices, formats, experiences, and scholarship, the contributions analyze many facets of digital feminist contention, including resistance storytelling, hashtag activism, grassroots journalism, or diaspora podcasting. This international and interdisciplinary volume will interest students and scholars of Media and Communication, Social Movements and Activism, Cultural Studies, Gender and Queer Studies, Race and Ethnicity.
