Starting from the idea of justice as being indivisible, this article examines the relevance of theorizations of the intersection of oppressions in the context of francophone Quebec feminism to demonstrate 1) the existence of a prototheory of intersectionality among radical feminism in the 1970s in Quebec and 2) that contemporary Quebec feminists are well positioned to propose a synthesis of the US-based intersectional approach and French materialist feminism. This argument also refutes two false accusations concerning intersectionality: its postmodern character and its propensity to fragment the feminist movement.
