Examining countries not often connected in the same research¿Colombia and South Africäthe book asserts that homophobia, as a form of gender and sexual violence, contributes to the transformation of gender and sexual orders required by warfare and deployed by armed groups. Anti-homosexual violence also reinforces the creation of consensus around these projects of change. The book considers the perspective of individuals and their organizations, for whom such hatreds are part of the embodied experience of violence caused by protracted conflicts and social inequalities. Resistance to that violence are reason to mobilize and become political actors.
