Libertarians should talk with the Left and need to learn how.
First, allow me to define what I mean by libertarian. I use a broad definition to define libertarian. I’m an “old fashioned” libertarian, as I still hold the same basic principles of libertarianism that were present when I got involved with it back in the 1970s.
For me, someone who supports depoliticized markets is part way there, but only part of the way. Depoliticized, or free markets, also mean private property rights—including the right to collectively own property—voluntary exchange between consenting individuals, and the right to keep the fruits of one’s labor.
Someone who believes in a peaceful foreign policy is also part of the way there. They would oppose interventionist wars, support international trade and the free movement of goods, capital and labor.
The third leg of the libertarian stool, so to speak, is civil liberties. By civil liberties, I don’t mean just those civil liberties that conservatives could embrace, such as the right to bear arms, nor do I just mean opposition to the PATRIOT Act. I also mean things such as ending the war on drugs, opposition to censorship, supporting separation of church and state—even at the state level. I mean opposition to sodomy laws and opposition to restrictions on birth control and abortion, I am talking about opposing things such as e-verify as well. I mean the whole plethora of infringements on civil liberties, including regulations restricting the right of people to enter into marriage contracts.
By libertarian I mean someone who is good on economic policy, foreign policy and civil liberties. This is not a 2-out-of-3 game, where you are a libertarian if you are bad in one of these areas. I would accept someone as libertarian if they miss the boat here or there; but not if they are broadly bad in one category. They may be a progressive, a conservative, a paleoconservative, etc., but they are not libertarian.
Libertarianism is not a variant of conservatism.
