For an agonistic conception of domestic conflicts. This paper addresses an issue that has been neglected by political thought and by feminist work focused on critical heterosexuality studies: the interpersonal conflict that arises when heterosexual partners try to adapt their intimate arrangements in order to attain greater equality. This article questions the limitations of political thought regarding power relations in the public sphere, as well as the silence of feminists regarding the domestic conflicts that can arise during the transformation of heterosexual relationships, relegating them to personal problems rather than political issues. Whether conflict occurs in the public sphere (in a democracy) or in the private sphere (in a couple), it is an inherent part of life due to plurality and the possibly divergent interests of the partners. Inspired by agonism, this article suggests looking at interpersonal conflicts in a positive light in order to conceive them as a means of political action in the private sphere. The paper is organized in three parts. The first links the politicization of inequalities in heterosexual relationships with the inevitable experience of interpersonal conflict. The second deals with the contribution of the agonistic tradition of political thought to the reflections regarding conflict in the personal sphere. The third discusses the major impact of conflict in feminist struggles to transform everyday heterosexual arrangements. In sum, the article aims to provide a portrait of an agonistic conceptualization of interpersonal conflict.
