Seen in the comments at Robb’s:

The more I think about it, the more I’m convinced that the only solution may be to kill off that 80% of the voters. Problem is, I can’t think of any philosophy which would justifiy politicide of that scale in support of libertarian ideals. Either you have the right to decide your own opinions, or you don’t.

While the commenter says he can’t justify it, the other question I have is who decides who lives and dies? I am for gun rights, but I am somewhere between neutral and against on drug legalization, for instance. So do I live or die? The number of political positions in this country are about as numerous as the population, and to simplify it to us v. them is naive. If you decide to kill everyone that does not share your position, you will set yourself against almost everyone.
