Most libertarians I know are men, and that should tell you something. Honestly, they're often politically liberal people who just can't accept the word "liberal" because it's so emasculating.
I often wonder if Libertarians aren't really fighting an unconscious and unspoken war against women in which some nebulous "government" is merely the stand-in for the real source of their powerlessness and angst.
Republicans have never been good at predicting the future. If they were, they wouldn't be Republicans.
