I'm not quite sure what exactly your critique of "liberalism" per-se is, but perhaps that's because we define the term differently? I see "liberalism" as a matter of focus-direction, at least in common-parlance, in favor of social change, contrasted against conservatism, which holds onto the status-quo and elevates the past/a mythic version of the past.

Liberals and conservatives can disagree in where society should go, while still retaining these basic orientations.
