Oh, I don't know about that; I have never seen any philosophical incompatibility between libertarianism or Objectivism and lynch mobs, so long as said lynch mobs are true mobs and not organized by a state actor -- the SA, for example, wouldn't qualify, but some of the Black Hundreds probably would. The "self-interest" idea covers such matters quite handily: it is, after all, quite plainly in one's self-interest not to do things which move his neighbors to organize a lynching bee. So, you know, an atrocious and unconscionable doctrine appealing only to people who have some serious problems with thinking of other people as people, yes, but hypocritical? Nah, not so much.
