Yea but you also agree with him on climate change. Specious reasoning. Feminism has a long history in the US dating back to the late 19th century and the drive for suffrage and prohibition movement but you two are underselling the womens movement of the last half of the 20th century which became much more militant in the 1970's where I have personally witnessed in my life time radical changes both in academics and in the work place for women.
Much of what has been accomplished by the feminist movement has changed focus over the years. Prior to 1950 it focused on equal rights before the law, i.e. marriage rights, children custody rights, voting rights, civil rights, contract rights, property rights, etc. That's what you and SF are referencing.
Things changed radically in the feminist movement in the 1960's to the 1980's which changed the focus to sense of cultural, political and economic injustice. It was during this period that women organized against institutionalized discrimination in academia and the work place and had a great deal of success in breaking through glass ceilings. Though that mostly had a limited impact to upper middle class women.
The womens movement then changed it's focus in the late 80's to focus on more global and universal issues such as rape, incest, prostitution, economic exploitation, procreation, racism, homophobia, sexism and classism. Those are womens issues that transcend economic, cultural and political classes as they affect most, if not all, women. This has been the era of radicalization as it has been a major paradigm shift from macro-political inequality issues, in which much common ground can be found with men, to micro-political issues that often challenges the traditional views and notions of the roles of women in society. In other words it's been a shift from a focus on injustice and inequalities to a focus on self determination in defining femininity and womens roles in society. It is this view that has polarized the political right, particularly men, in recent years and threatens men as there has been a sustained attack on male dominance of our political systems. That's why you see many men, particularly on the political right, attempting to marginalize the current womens movement as "Feminazi's" as it threatens their paradigm of what womens roles should be. It has also had the impact of bringnig far more women into the movement as it is currently focused on more universal issues that appeal to a far wider population of women than the movement had in the past.
