Libruhtarian
Libruhtarian is an alternative to libertarian, meant to highlight the stupidity and internal inconsistencies of their ideology. It comes in two variants: "Libruhtarians" (with a capital "L") are even dumber than their small-l cousins.
Libruhtarians claim to support a national defense, at the same time as they support open borders. Those open borders would allow authoritarian regimes to in effect colonize parts of the U.S. by sending their people here, thus showing that libruhtarians don't really support defending the U.S.
