Left libertarian here -- as I knew most of us would be before I even voted or scrolled down the thread.
I'm a little worried; I turned out more centrist than I expected.
I have no idea how someone can be both left and libertarian. Aren't libertarians those guys carrying assault rifles around in Target all the time?
Those people aren't Libertarians ;). They have one right they care about and you'd better agree or else (Authoritarian). Additionally, they prefer the free market decide everything (Right). These people are Right Authoritarians, not Libertarians. Libertarians are about personal freedom, the right to choose your own life, etc.
In the US, the "left"/"right" system actually sits on the y=x line where "right" is really Right Authoritarian and "left" is slightly less Right Authoritarian with the greens representing where most of us stand on the "extreme left". Sorry to those mustachians that fall more towards the y=-x line. You're either a "traditional" republican (Right Libertarian) or a communist (Left Authoritarian).
This is why so many people in this country feel disenfranchised and/or pissed off at the government: they
want to vote "left libertarian" (or maybe "right libertarian"), but both major parties are authoritarian.
It doesn't help that the entire "right vs left" terminology the media uses obscures the issue, since (as this topic shows) political views cannot be expressed on only one axis.
The correct answer to the question "are you liberal or conservative?" is always "fuck off, you ignorant tool of the establishment!"
regardless of what your ideology actually is.
