I think you describe SOME feminists.

However, many other feminists can see there really are biological differences, differences on trend. These feminists I would say believe that the natural tendencies do not need to be further reinforced by laws. That the fact that more women than men will nurture children while more men than women will run corporations in the cutthroat way required for success does NOT suggest that we should have laws that make it harder for men to raise children or for women to be CEOs.

But you are correctly warning against the stupid end of feminism in my opinion.
