Yes, I am sure you have no idea why I mention Hayek, because you are ignorant of libertarian philosophy. You could also not be more wrong about Mises, who never endorsed Marx and quite the contrary, was the polar opposite in most respects. As for his personal sexism, I can't really say, but if that allegation is true it did not have any impact of libertarian thought, clearly.
These luminaries, Hayek and Mises, are founders of libertarianism. You know, that thing you use as your lean. (I am sure this is news to you. I don't know what you are, a Randian, maybe? Or just a Republican-in-libertarian-clothing, as I have suspected?)
Rothbard, however, is the greatest of them all. Mises and Hayek were excellent economists but they did not have the breadth and gravitas of Rothbard as a philosopher. The only other libertarian philosopher to have his intellectual heft was Nozick who came along much later.
Anyway, you call yourself a libertarian, but like so many self-described libertarians you know nothing of any of this.
