I've kind of skimmed through a bit here. I think there IS benefit in being as specific as possible with points both to avoid confusion and to prevent those who disagree accusing you of you being too generalised and therefore dismissing your arguments out of hand.
I think there is a huge danger in saying men are like this and women are like that, which follows a biological argument. Such arguments are popular amongst misogynists because they depict traits, characteristics, behaviours, attitudes, interactions, etc. as something innate, immutable and uncontrollable. In other words, men are at the top of the tree, just learn to live with it and stop whining.
Cordelia Fine is often name-checked here as someone who has blown huge holes in all those biological determinist theories, but it's worth mentioning this again I think. I don't believe male and female humans are motivated solely or even primarily by the urge to reproduce. If anything, I wonder if sex is pleasurable as the carrot to get people to procreate! That would explain why many Lesbians, gay men, bisexuals, straight couples, transgendered people, etc. still form happy relationships with other people, still enjoy sex but do not choose to reproduce.
Really though, I believe the mechanisms of power, privilege, control and oppression aren't due to biological sexual differences (any more than those relating to ethnicity, class or sexual orientation are down to nature.) It's all due to social conditioning. SO, coming back to the earlier point of the discussion, it's surely more accurate and less debatable to say, "men tend to be socially conditioned to be X while women tend to be socially conditioned to do Y." That allows the understanding that there are people who buck the trend whether through having an atypical upbringing or through individual choice. It also recognises that gender stereotypes are foisted upon us, are present from birth, are all around us, just part of the furniture, which makes them more difficult to pinpoint and tackle (as they are seen as "normal.")
It also frames the concept of patriarchy and the institutions that promote and sustain systems granting some more power and privilege than others in such a way that it can be argued as damaging for ALL, not just for those lower on the totem pole.
Just a few musings while sorting through the holiday decorations! :)
