"Why Are Libertarians Mostly Dudes?"

That's a New Republic article by Jeet Heer.

[T]he typical libertarian is a white man. These firm demographic contours cry out for an explanation since, at first glance, there doesn’t seem much intrinsically white or male about libertarianism. Proclaiming itself a philosophy of individualism, with no overt celebrations of either patriarchy or racism, libertarianism still ends up being monochromatic and male....

Jesse Walker, an editor at Reason magazine, agrees that the libertarian gender gap is real... Aside from computer programming, libertarianism overlaps with other male-dominated subcultures as science-fiction fandom, the gaming community, Men’s Rights Activists, and organized humanism/atheism. But this account simply raises another question: Why do overwhelmingly male subcultures feel an affinity for libertarianism?...

While libertarianism is rarely explicitly sexist, it is hostile to collective efforts to challenge sexism: anti-discrimination laws, affirmative action, paid leave, and the broader net of social services that are particularly necessary to those who have historically been tasked with care-giving jobs within the family. No wonder women as a whole find little in libertarianism that appeals to them....

 This [nostalgic] yearning for the America of the Robber Barons has little to offer most women (who might not want to return to a world where they couldn’t vote and had severely restricted social lives) or for that matter most non-whites (who might recall Jim Crow segregation)...

This is what I felt back in 2007 when I had my in-person interactions with a group of libertarians. From the archive:

"Where I was when I was out of my milieu."

"Responding to Jonah's response to that hot diavlog."

"Here's the post where I take on Ron Bailey of Reason Magazine."

"Adler, Drezner, and Levy try to close the glass window on debate, and I say, Aw, come on, you're not gonna say that now."

To put it very plainly and simply, to me, the libertarians lacked humanity and they were using their pride in their commitment to abstract ideas to resist examining the reasons why they liked the ideas they were wedded to. I think people like that would be very dangerous if they had political power. Intellectually, as people to converse with, I found them cold and rigid, not interested in talking about anything on the level that I am seeking, and creepily eager to insult me for being on the wrong level.
