Men and women are not that different. Using that excuse is an over-complication. And points to another male priviledge. Present work patterns, and business practises have been designed by and for a male workforce...thus, for example, the lack of constructively working maternity leave and child care into the business culture. Males have had the priviledge of not having to choose between a job or a family.
We are not talking about the world of the post-WWII when women were only given the right to vote a generation before, race laws still common, and we were the last ones standing strong economically after over a decade of world war. Since we cannot go back to that, society will need to adjust to the new concepts of equality that are evolving. Systems created in earlier times that have elements that favor one gender or race over others will slowly change. Reconizing male priviledge is part of that change -- not to punish men or lable them as oppressors, but to start the discussion about what the changes can and will be.
Fun fact: The f64 group was one of the first artist movements that included women as active members.
