A central tenet of modern feminist thought has been the assertion that "all women are oppressed." This assertion implies that women share a common lot, that factors like class, race, religion, sexual preference, etc. do not create a diversity of experience that determines the extent to which sexism will be an oppressive force in the lives of individual women. Sexism as a system of domination is institutionalized but it has never determined in an absolute way the fate of all women in this society. Being oppressed means the absence of choices. It is the primary point of contact between the oppressed and the oppressor. Many women in this society do have choices, (as inadequate as they are) therefore exploitation and discrimination are words that more accurately describe the lot of women collectively in the United States. Many women do not join organized resistance against sexism precisely because sexism has not meant an absolute lack of choices. They may know they are discriminated against on the basis of sex, but they do not equate this with oppression. Under capitalism, patriarchy is structured so that sexism restricts women's behavior in some realms even as freedom from limitations is allowed in other spheres. The absence of extreme restrictions leads many women to ignore the areas in which they are exploited or discriminated against; it may even lead them to imagine that no women are oppressed.
