In “More Pseudo-Libertarianism,” I say that I must come up with a new name for left-libertarians, inasmuch as they are not really libertarians. Some of them have tried “liberaltarian,” an amalgam of (modern) “liberal” and “libertarian.” To be a “liberaltarian” (with a straight face), one must believe that leftists are willing to abandon their pursuit of all-encompassing government and join left-libertarians in their pursuit of absolute fairness (by whose standards?) in economic and social outcomes. Leftists seek the latter objective, but will never be persuaded to drop the former one.
All of which suggests that a left-libertarian is really a (witting or unwitting) collaborationist: an intellectual Vichyite or, in the parlance of the 1950s, a fellow traveler or comsymp (communist sympathizer).
Comsymp has a certain ring. Perhaps “libsymp” is what I’m looking for. I’ll give it a try.
