More people means more positions, more dialogue, more voices, more cacophony. The belief that women and men are, and have been, treated differently by our society, and that women have frequently and systematically been unable to participate fully in all social arenas and institutions. A desire to change that situation. It does not follow the classical Aristotelian genus-species structure of definitions, yet clearly refers to and identifies an aspect of reality. His mistake is the presupposition that such a genus must be an ideology.
Feminism describes activism and a commitment to action as much as a range of ideas.
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.
