Okay, look at it this way.
Libertarians in my experience focus exclusively on tying the hands of government. They tend to almost have a "know-nothing" approach to the issues, instead single-mindedly focusing with a laser-like obsession at preventing the government from doing anything. They are very much black and white in their view of the world.
The best example is the recent anti-SOPA protests, which is largely libertarian.
Libertarians didn't really pay any attention at all to the issue of property rights for content creators, instead dismissing them as "big business" and focusing on the worst possible over-reach by these new government powers.
Or say, fuel-mileage standards. Libertarians are against regulations, but they also tend to be against gas taxes also. THey are against any government action typically, viewing it as a slippery slope towards a totalitarian (the black and white thing again) state.
So Libertarians seem to always err on the side of government restraint. On the issue of abortion, pro-choice is the side of government restraint, and pro-life is the side of government intervention. Yet, Ron Paul favors government intervention.
Then again

pretty much paints a picture of a traditional conservative guy. He's not like a Reason magazine- level libertarian. So I think it's fair to say that Ron Paul isn't really much of a libertarian. He's more of an old-style conservative.
