I'll never forget a girl I had a crush on in high school saying about Ron Paul "he's a libertarian, he's basically an anarchist." Vibe killer.
Which is another thing as Jer sort of pointed out in the terrible music thread about Frank Turner, is that some really young punks (8th grade ish?) get into libertarianism via punk while still trying to figure out what all these political words mean (at least anecdotally for me was the case with kids I knew, like that girl). Most grow out of it once they just learn some shit about how the world works (which she did).
