Here’s an article from Gina Luttrell at Thoughts on Liberty. In one way, the article is a defense of libertarianism against a common rhetorical attack from political status-quo Progressives. In another way, — and for much the same reason, because of the libertarian ideal that it appeals to — it is also a challenge to actually-existing libertarians. This is in many ways what the ideals, priorities and focuses of a sane Liberty Movement ought to be. If what you’re doing doesn’t live up to that, then you need to think more about what you’re doing, and why. Here’s Luttrell, in Tales of a Non-Male, Non-Christian Libertarian:

. . . In the history of mankind, who has been the most responsible for death, destruction, and oppression? Government. States are the entities that wage needless wars to prop up their own economies. Governments are the ones that systematically hunt down and slaughter their own peoples. Governments were responsible for Jim Crow, and it was the laws of the day that condoned, regulated, and perpetuated slavery. Even in our country today, a liberal, Democratic government is responsible for the mass incarceration of millions of people who have harmed no one. It is because of government policies that two people of the same sex can't share property, have hospital visitation, or in some cases adopt children.

To my mind, and to the mind of many libertarians, the real enemy of the non-white, non-male, non-straight, non-Christian people in this country is not libertarianism, but the government. And when you greatly limit or even, dare I say it, abolish government, you free millions of socio-political minorities.

I will freely, perhaps more freely than most, admit that libertarians royally suck at understanding the societal oppression that faces minorities in our country today. I am about to make a trip to a conference to make that argument to them. They outright deny it in some cases. But not all of them do. . . . I don't deny that libertarians very often have issues recognizing these problems as legitimate, but there are also scores of them who do and who are developing free solutions for a free world–for everyone. This is not a problem of libertarianism, it is a problem with some libertarians, and it is a fixable problem.

Are there problems with libertarianism as a philosophy? Possibly–but that depends on what type of libertarianism you're talking about. . . . Libertarianism is a multi-faceted ideology, with a diverse group of adherents who all think different things about what liberty means and how best to achieve it.
