User blog comment:Neowitch/757 - The most disappointing female character in all of OP/@comment-2226235-20140820134328/@comment-10543621-20140822062902

I think we have to just accept the fact that Shonen mangas inevitably will focus more on male characters. There will be female combatants, but their role tends to end up more or a support type, like healers (Like the general push towards females being medical nins), and they'll seldom take the role of the main fighter (like Nami and Robin). Which might not be a bad thing, and not necessarily sexists if we just look at it in a way doing what you are suited for.

The Qunari's (Dragon age) way of thinking comes to mind, where they assign people to their suited roles, and they genuinly believe that women are just more suited for administrative roles. In the same way like in Naruto's context,. the females tend to be better at chakra control, hence their suitability as medical nins. In One Pieces context, I think the women tend to be smarter, and hence take a more supportive role (navigator, archeologist) as opposed to the meathead idiots (i.e. Luffy).
