In my experience as a psychotherapist . . . men are much more easily threatened by a woman's success and power than another man's power. For many guys, this is how they were raised, which can lead to them experiencing difficulty with aggression coming from females. Many men are socialized to compete with other men for power, but are not equipped for the "aggressive, powerful female". The lack of experience some men have with successful, agressive women is too much for them to handle and they "revert" to what they were taught at home.
I think it is totally silly to view a woman's right of authority as any different than a man's. However, there are plenty of men who haven't been able to make the adjustment and the "old ways" flourish in those communities.
I have counseled a number "power brokers" from the business world to Capitol Hill, and it's amazing how many men have "Mommy" issues that totally dominate how they carry themselves in the world. "Mommy", for many, was the first experience with "the aggressive female", and that interaction has a lot to do with how that person behaves today.
