Libertarians subscribe to an ideology that emphasizes people caring for themselves ... this is obviously going to piss a lot of people off.
Well, yeah, when you're a single parent working two jobs to support your family and some pasty string bean wearing a bowtie knowingly intones that you should be thrown off Medicaid because 'something something personal responsibility' it's only natural that you will regard that person as an entitled a**h*le.
As for the OP,
all true believers are smug and annoying; such is the fate of those who decide they've figured everything out and are waiting for the mindless rabble to catch up with their brilliance. The difference is that whereas the membership of each of the major parties is quite large, thus diluting the smugness of the true believers is with the watery allegiance of casual voters, the Libertarians are a small party, and so true believers make up a larger percentage of their vocal supporters.
