Feminism is defined as
Feminism is a collection of movements aimed at defining, establishing, and defending equal political, economic, and social rights for women.
in Wikipedia and
A social theory or political movement supporting the equality of both sexes in all aspects of public and private life; specifically, a theory or movement that argues that legal and social restrictions on females must be removed in order to bring about such equality.
in Wiktionary. Masculism is defined as the exact same but with equality for men's rights, which actually means the same.
I think that this is in fact a wrong use of the word feminism which puts emphasis on the word women (~ Latin femina) instead of equality between sexes.
I'm looking for a word that represents a movement which can be assumed and extremist feminism and that supports more or better rights for women above men. Or just supporting more women's rights regardless of those of men. This is what I would think of when hearing feminism, until I discovered this wasn't true.
