While I don't like the extreme True Scotsman purists who try propagate their version of libertarianism as absolute truth, me thinks this website makes a pretty broad interpretation of what is libertarian.
a lot of interent libertarians think so. Alan Greenspan considers himself to be a libertarian, and i will respect the fact that he wants to be labled as such.
Glenn Beck also describes himself as a libertarian. I hate purism, but I flat out refuse to acknowledge any possibility that he might have anything to do with me ideologically.
