Feminist ideas are those that lead to social progress concerning gender relations at a given time and place. Objectivism was designed in a hierarchical way as a philosophy, including an emphasis on thought and cognition as fundamental and other mental aspects and activities as derivative. Correct thinking about the right ideas'' would be sufficient to call oneself an Objectivist, but it is not enough to be a feminist. Without a commitment to action and social change one is not a feminist, even if one holds feminist ideas. So in feminism there is a form of ''equal worth'' between ideas and activism.
Feminism is more than an ideology, more than a philosophy.
This is why feminism, unlike Objectivism, cannot be defined by a genus which is only an ideology or a philosophy. And in the Western world today it means a fight against tacit and institutionalized collectivist and misogynist beliefs derived from gender roles and other sex-based prejudices. The common thread running through these different periods and places is captured by the definition above. It involves a theory about and a commitment to men and women being equals, in all spheres of life. Equals in standing, possibility, freedom and range of choice.
