If you have some time to read a good article on the subject of sex and gender roles, I recommend this one.
Feminist (and many other!) theorists generally accept that values are socially constructed and historically acquired, but they seem to think they must nonetheless be preserved. There are two typical variants on this position. One says we must distribute masculine and feminine values throughout the whole of humanity; the other says that masculine and feminine values must each be maintained in their original group. The latter view is currently especially common among women who do not want to share feminine values with men. I am not sure whether this is because they believe men are unworthy or incapable of sustaining these values, or because they know men do not want them anyway. But we might well ask how women who are ‘nurturing’ and proud of it are going to become the equals of unchanged men—who are going to continue to drain these women’s time? This is not a minor contradiction. It shows, rather, that if intellectual confusion produces political confusion, it is also possible to wonder, in a mood of despair, if there is not, behind the intellectual haze, a deep and unacknowledged desire not to change.
