An Ideology that supports that women are superior to men, whether biologically, socially, or mentally. Common to contrary belief, Feminists support sexism with female bias. If feminists really did want sexual equality, they would be called 'Human Equality Activists', and not 'Feminists'. As you can see, the word 'Feminists' stems from the word Female. If the movement DID support true equality, then the word would not be based off any sex as to avoid bias.
Feminists are supporters of Feminism, are also referred to as Feminazi's.
