 In each of the cases of being oppressed as a woman mentioned above, Paula suffers injustice, but a crucial factor in explaining the injustice is that Paula is a member of a particular group, viz., women. This, we think, is crucial in understanding why sexism (and racism, and other -isms) are most often understood as kinds of oppression. Oppression is injustice that, first and foremost, concerns groups; individuals are oppressed just in case they are subjected to injustice because of their group membership. On this view, to claim that women as women suffer injustice is to claim that women are oppressed.
