 When domination imposes the terms of the revolt 
Focusing on the case of “homosexuals”, this paper highlights the relevance of Colette Guillaumin’s contributions for the study of “sexuality” or “sexual orientation”. Her materialist approach receives little attention in this field, partly because it mostly deals with “race” and “sex”. It nevertheless contains precious tools for denaturalizing “sexuality”, and for considering its naturalization by discourse as both an effect and an instrument of concrete power relations. In addition, it can form a useful framework for the study of discourses of resistance to categorization. The paper briefly introduces two examples of those discourses of resistance, namely the problematization of « homophobia » and the proliferation of categories promoted by queer theory. It then explores Guillaumin’s theoretical contributions for analysing the (de)construction of “homosexuals” as a category.
