The article was about how a libertarian point of view allowed ‘evil’ to occur. I don’t think that’s true of an authentic libertarian point of view, but only of the self-serving, pseudo-libertarian, no-regulation-at-all-ever-if-it-costs-me-profit point of view.
I suspect that there aren’t very many people who actually comprehend libertarianism, and a whole lot of people who embrace no-regulation-at-all pretend libertarianism because that’s what some radio-talk-show pundit told them to think. This is not based on a statistical survey, but only on informal observation of who gets on the news, and what they blabber. I’m sure it doesn’t apply at all to you.
