Our starting point is that socialists should engage positively with those fighting oppression but that such an engagement is not helped by hiding our theoretical differences. As such we analyse privilege theory and intersectionality, and their strategic implications, from a Marxist point of view to show how and why we differ. We argue that privilege theory, by concentrating its focus primarily upon individual relationships rather than the oppressive system of capitalism, tends to direct people away from the kind of social solidarity necessary to beat oppression.
