First of all Who is Murry N. Rothard? I looked for the most negative Biography I could find and after a few pages I had to resort to the most reliable source of Negative Info on Anyone who stands for anything that doesn't push the Agenda of the Progressive Movement:
http://en.wikipedia.org/wiki/Murray_Rothbard

n ote - Keep in mind that Murry came from the Columbia University Leftist/Communist Machine(Bill Ayers and Weather Underground, Eric Holder, Barak Obama, Richard Cloward of "Cloward and Piven Strategy", Funded by George Soros, and MANY MORE).
