I'm sorry his viewpoint opposes your worldview, but there are both physical and psychological differences between men and women across the world(https://en.wikipedia.org/wiki/Sex_differences_in_psychology). Those differences don't stem from nothing: The act of giving birth and nurturing a child for years means it's biologically very expensive for women to breed. This leads to a sexual strategy that requires the mother to be much more selective than men. You see it in the gender norms across the world, where men tend to be more aggressive, assertive, and womanizing while women tend to be less competitive, more nurturing, and more selective towards their mates. You can recognize the general differences between the sexes and still fight for equality.
