One more time:
Libertines: Anything goes, if-it-feels-good-do-it.
Liberals: In their modern incarnation a totalitarian group bent on doing whatever they want while enslaving the rest of the world for fun and profit, for its own good.
libertarians: The government which governs best governs least. Proponents of limited government (like our Constitution was supposed to provide) not to be confused with a political party of a similar name, although there may be a few libertarians there.
Nope, exactly the same as a federal judge and they're all leftwingtards.
