"Libertarians: Never got over the fact they weren’t the illegitimate children of Robert Heinlein and Ayn Rand; currently punishing the rest of us for it. Unusually smug for a political philosophy that’s never gotten anyone elected for anything above the local water board. All for legalized drugs and prostitution but probably wouldn’t want their kids blowing strangers for crack; all for slashing taxes for nearly every social service but don’t seem to understand why most people aren’t at all keen to trade in even the minimal safety net the US provides for 55-gallon barrels of beans and rice, a crossbow and a first-aid kit in the basement. Blissfully clueless that Libertarianism is just great as long as it doesn’t actually involve real live humans.
Libertarians blog with a frequency that makes one wonder if they’re actually employed somewhere or if they have loved ones that miss them. Libertarian blogs even more snide than conservative blogs, if that’s possible. Socially slow — will assume other people actually want to talk about legalizing hemp and the benefits of a polyamorous ethos when all these other folks really want is to drink beer and play Grand Theft Auto 3. Libertarianism the official political system of science fiction authors, which explains why science fiction is in such a rut these days. Libertarians often polyamorous (and hope you are too) but also somewhat out of shape, which takes a lot of the fun out of it.
Libertarians secretly worried that ultimately someone will figure out the whole of their political philosophy boils down to “Get Off My Property.” News flash: This is not really a big secret to the rest of us."
