I chose "Hurt" because to me, he is not a libertarian being that he supports an aggressive war and is anti-immigration. Two big anti-freedom beliefs and he keeps spouting that he is a libertarian. So most folk hear what he says and jump to the conclusion that when he calls himself a libertarian that must mean that, that's what libertarians are all about.
Like when I was watching the 2004 LP convention and there was some crazy blind guy in a wheel chair ranting and raving for a big chunk of time about all kinds of non-libertarian things. Now this person does only hurt by saying he is a libertarian when it is crystal clear that he is the farthest from, but your average Joe and Jane six-pack tuning in to see what the LP is all about doesn't know any better and think we're all like him. Same with Boortz except he is on every night mis-representing libertarianism.
