This ethnographic study of a high school gay-straight alliance club examines unintended consequences of silence during the Day of Silence, a day of action aimed at addressing anti-LGBTQ bias in schools. While this strategy calls for students to engage in intentional silences to raise awareness of anti-LGBTQ bias, it does not necessarily lead others to address harassment or silences around gender and sexuality. Rather, silence makes students more defenseless in the face of verbal harassment. (Contains 1 figure.)
