Both ideologies evolved from the same source of classical liberalism, and still share plenty in common today.

But liberals would definitely down-vote me if I talked about Rothbard and Mises. Why do you think that is?

Because they have a difference in opinion with you about the degree to which markets should be allowed to exclusively allocate resources?

I personally am in favor of free market. Are they? I do not shy away from being a minarchist either, to be honest.
