Feminism is simply, equal rights for women. If your anti-feminist then your anti-equal rights for women. Go and look up whatever reliable dictionary you want. Sure there are some feminist that don't want equal but superior rights for women but then, I would argue that the same is for racism. A surprisingly large amount of people I've seen support positive discrimination, that's racism. Yet you don't hear people stating they are anti-antiracism now, do you?
