Nick Gillespie/Matt Welch: "While there are competing definitions of what 'libertarian' means, the simplest understanding attaches to people who believe that government is less efficient than the private sector, that people should be left alone as much as possible to lead their own lives, and that tolerance is the most important social value."
David Gordon: "Libertarians are committed only to defining the permissible use of force. They are free to adopt whatever attitudes they wish towards people's lifestyles, so long as they respect rights. They are emphatically not required to be 'social liberals'".
I like both Reason and the Mises Institute. Yes, you can like both.
