"This manifests itself in the faulty assumption that men are more effective leaders than women and that qualified women do not exist."

This is not necessarily a faulty assumption.

In my experience - on a per capita basis - men ARE more effective leaders than women. They are usually more subjective, they tend to be much more fair with subordinates who they may not personally like but appreciate their ability to get work done, and they don't run for cover when the going gets tough.

Yes, there are exceptions, and some women leaders are great. But in general, from real life experience, men tend to be better leaders and women better nurturers. Sorry if that doesn't make you fell all warm and cozy, but that's my reasonably well substantiated position.
