You are foolish to pretend that there is no masculine nature nor feminine nature.  How many women do you see in the field of math and physics?  How many men do you see in teaching pre-schoolers?  How many women do you see signing up for combat in the Marines?  How many men do you see wearing sexy negligee?  The list goes on interminably, and unless you've been so thoroughly indoctrinated, so utterly fooled, as to say there is NO DIFFERENCE BETWEEN MEN AND WOMEN --- guffaw --- you already know the list pretty well.
