There are many jobs that are still dominated by men or by women, but the question I find most fascinating is women in the military.  Right now, women are not supposed to serve in combat positions.  However, the women are in the war zone.  They are in combat, whether we want to accept it or not.  It's time to give them respect.

I agree that there are only a handful of specialized jobs better suited to one gender or the other. Many of our gender-specific views of who should have what job are simply historical and not based on anything but the fact that we have always seen that job filled by a particular gender. 

For instance, the job of being a football referee or a baseball umpire is not better suited to one gender or the other. Yet we have really only seen one gender perform the job.

I tend to agree with you (I'm a man who quit working full-time to be the main child care-giver for the family), but I think that we have to distinguish between things that one sex is innately better at and things that they are better at because of socialization.

In other words, I don't believe that women are, for example, inherently better at being grade school teachers.  However, they may be socialized to be better because it may be that they are trained by our society to act in ways that are more suited for that particular job.  So there's a difference between saying one sex is naturally better at something and saying that our society molds them to where they are better at it.
