I think you, and the author, are missing a key distinction. There is feminism, which entails pretty much all of the good aspects of feminism, and then there is Feminism, which appropriates a few of the good aspects to shield itself while it pushes the societally destructive aspects. It is the classic stolen concept, a mainstay of communist ideological doctrine.
Lower case f feminism entails all the things like the right to vote, equal protection under the law, fair treatment, workplace access, opposition to abuse etc. Those fights are all either already won, or organizations like NOW are not bothering to fight them anyway.
Capital F Feminism is pretty much about pushing the socialist (pronounced Communist) wing of the democrap party. Take for example NOW's opposition to vouchers. It has nothing to do with feminism. That is about opposing capitalism in education so that the government monopoly on education can continue to fail miserably to the detriment of our whole society.
I think I can safely describe my lovely fiance as a feminist; but certainly not a Feminist. She is intelligent, well educated, with professional job skills and experience. She is an independent and whole person; she is not societally bound to 'find a husband' as perhaps she would have been a century ago. But the fact that she does not 'have to' find a husband does not mean that she cannot find happiness in a shared loving relationship. She does not have to accept the Feminazi position on everything. She does not have to support the destruction of family and civil society in order to have the title feminist.
