Ugh. Vice. Libertarians. Bleh.
I always suspected that the only right libertarians believe in is the right of the rich to screw the poor and that it reflects the "I've got mine, fuck you" attitude that so many conservatives have.
Until I read your blog post, though, I never connected privilege with their thinking. It makes sense. Also, I've worked with one gay libertarian. He owned his own house and wasn't open about being gay. We came out to each other about a week before I left that job.
