You obviously don't know the difference between an anarchist and a libertarian.
Some Libertarians express their beliefs in extremes. It is their expressions which largely form the public image.
Surely there must be some way to express being Small Government, Economic Conservative, Social Liberal. The Libertarian party has done a poor job of controlling its message to project a less extreme image. This from Gary Johnson and Bill Weld is a good start -- if people get to see it.
