National discourses, forms of ethno-national belonging, and nationalist values are said to be based, since the 18th century, on heteronormativity, gender binarism, sexual dimorphism, and, consequently, on the regulation or invisibilization of sexual and gender diversity. In recent years, I have focused on technologies of national identity management related to governmentality and biopolitics, as well as on the uses made of academic productions (especially anthropological ones) to shape the discursivity that regulates sexual and gender diversity. Based on my experiences of multi-sited ethnographic research, I propose a theoretical debate aimed at decentering the gaze on expressions of sexual and gender diversity which could lead to a subversion of the order of things and to the proposal of another possible common world against the necropolitical expansionism of the new moral crusades.
