To write or talk about how women and men are different, make sure you portray whatever attribute you ascribe to women as better.
I was put in mind of this when reading about a study comparing women and men in the area of charitable giving and survey-taking.
This study also found that women were less likely to participate in surveys compared to men and concludes that women behave in this way because they have 'less dispersed distribution of altruism.'
Thus, women and men are equally altruistic, it's just that women are more focused in their altruism.
The other way of saying that would be that men are more inclined to help everybody, and women more inclined to help just friends and family.
But the second version favors the wrong gender,
and accordingly must be returned to sender.
