>I also don't see that much difference in asking "why don't more men do [some female-dominated profession]" vs. "why don't men fight for more men to do [some female-dominated profession]".

Really? The mere fact that someone would take these as different questions should suggest that they don't believe they would partake in campaigning as women do now, were they in the same position. Now, perhaps I'm wrong about myself-- people very often are-- but in this case I very much doubt it. Power, tech jobs, diamond rings. Women want none of these; they want the wanting. How to tell? That which they actually do want, they are far more goal-oriented about obtaining. Boyfriends, shoes/handbags, an appearance of not standing out, etc.
