Because libertarians define themselves in terms of pure ideology?

US modern liberalism, on the other hand, has basically no pure ideological component other than beliefs in humanistic morals, pragmatism and empiricism. (And, of course, pandering from politicians). Most of us really distrust overly strong ideologies, so that's what we poke fun at. Liberalism isn't the opposite of libertarianism in terms of ideology, we're not in favor of nationalizing industries, it's the opposite where we don't think there's a one-size fits-all narrative to define everything.
