Jeet Heer investigates a burning question today: why are most libertarians men? He offers several plausible explanations, but I think he misses the real one, perhaps because it's pretty unflattering to libertarians.
So here's the quick answer: Hardcore libertarianism is a fantasy. It's a fantasy where the strongest and most self-reliant folks end up at the top of the heap, and a fair number of men share the fantasy that they are these folks. They believe they've been held back by rules and regulations designed to help the weak, and in a libertarian culture their talents would be obvious and they'd naturally rise to positions of power and influence.
Most of them are wrong, of course. In a truly libertarian culture, nearly all of them would be squashed like antsmostly by the same people who are squashing them now. But the fantasy lives on regardless.
Few women share this fantasy. I don't know why, and I don't really want to play amateur sociologist and guess. Perhaps it's something as simple as the plain observation that in the more libertarian past, women were subjugated to men almost completely. Why would that seem like an appealing fantasy?
Anyway, this is obviously simplistic and unflattering, and libertarians are going to be offended by it. Sorry. But feel free to take some guesses in comments about why women don't take to libertarianism as strongly as men.
