A fairly good example of inconsistency.  In his Better Angels book, Pinker celebrates Norbert Elias’ Civilizing Process thesis that increased emphasis on etiquette and formal propriety played an important role in taming the casual violence of European societies.  Elias’ arguments (an earlier and much more thoughtful version of James Wilson’s Broken Windows hypothesis about crime prevalence) easily justify rigid standards about sexual harassment.  You can’t accept Elias’ arguments as valid and then turn around and excuse McGinn’s behavior.  Pretty thoughtless.
