I was wondering above, when I categorised the women's society as an equal one whether that was really the best categorisation of it - are we talking about equality or about something bigger - a society in which a variety of negative characteristics have been eliminated and only neutral/good characteristics are left.

I think it's fairly clear that there's more than just neutral/good characteristics left; that's why the society is not a utopia. For starters, as has been noted, it's less genetically diverse and less innovative--both things that I think, broadly speaking, are good. And I don't think there's anything to suggest that anger and aggression are completely absent, just that they are not present in extreme and destructive forms. So I don't think 'equal' is a particularly useful word to think of the society with; I prefer 'healthier (in many ways)'.
