Why is libertarianism so infallible?

It is due to it being the application of political science. It does not permit failed policies to be continued fruitlessly year after year with idealistic fervour, it is next to impossible for anyone surrounded by fierce libertarian critics to continue clinging on to lies. It is a purely functional machine, lubricated with justice and fueled by free speech.

>Libertarians are at least sane and are civilized

We have a comedian in our midst. Go read Forbes magazine and try to differentiate between warlord-style looting and libertarian-style voodoo economics. The only difference is that it's possible to convince morons that there's some imaginary benefit to libertarianism.
