Then consider a different intellectual profession dominated by women. 78% of publishers in the U.S. are women.[1] If I say that this is due to an innate differences rather than sexism against men in the publishing industry, am I saying that men are bad readers and stupid?
Also, can you clarify what you mean when you state that pediatrics is "an example that's a biological function primarily to do with women." Are you stating that women are innately (in other words, due to their gender) better suited to administering healthcare to minors as compared to men?
Just because women are the ones who birth children doesn't mean that I brought up "an example that's a biological function primarily to do with women".
64% of practicing gynecologists are men, but only women have vaginas.
You don't have to give birth to children to be a pediatrician or a gynecologist.
