I know an awful lot about your principles, by reading what you write. Observant, rational people know a lot about the principles of candidates by reading what they write, listening to what they say, and observing their actions. These people also know there isn't an ounce of actual liberty-loving, or even conservative, principle in Mitt Romney.
The Internet may be semi-anonymous, but what you say is still said, and I can still take the measure of you as a person, whoever you might be.
Now you're acknowledging that anarchists represent a small subset of self-identified libertarians. So what are you on about?
libertarian != Libertarian. Many self-identified libertarians are members of the Libertarian Party. Many self-identified libertarians are members of the Republican or Democratic Parties. Then there are a hell of a lot of self-identified libertarians who don't saddle themselves with any party affiliation. That you still can't fathom the distinction between libertarian and Libertarian is yet further demonstration of your willing subservience to Party over Principle.
