We talk with Mariame Kaba, co-author of “Interlopers on Social Media: Feminism, Women of Color and Oppression,” about the debate over “toxic twitter feminism.” Kaba calls out the anti-black rhetoric of white online feminism and challenges us to do better than false claims of “safety” and “inclusion.” And labor activist Maria Guillen talks about her experience growing up and how it led her to commit her life to activism.
