From what I’ve gathered, libertarians are basically socially amoral? If that’s the case. then no wonder they are considered more palatable to Hollywood.
On the contrary, I believe libertarians are quite moral, in that they don't want confiscate other people's incomes or tell them how to behave, unlike the left and the right.
YMMV, of course. I frequently see social conservatives prudishly refer to libertarians as "libertines". When describing my own libertarian-leaning views I was recently called (pejoratively, mind you) a "greedy Republican" on this very board. I took it as a compliment.
