This dossier names "queer security studies" as a new field that investigates what security and safety means to queer and feminist studies, critical military studies, and broad progressive movements. What counts as safety, and for whom? What kinds of material practices can scholars and activists engage with to make the world more secure for the most vulnerable? What are the repercussions of those practices? The dossier takes on these questions through discussions of rape culture, risk management and health in the contemporary US American family, the impact of neoliberalism on sexual citizenship in the United States and abroad, and narratives of safety in authoritarian systems like the state and the prison.
