A view filtered through Steven Pinker. Money quote:
David Sirota credits Ron Paul, who is popular among voters aged 18 to 29, for this generational shift. Sullivan invokes the hard lessons of the Iraq invasion, presumably formative for young adults. Both may be right to a degree: the Iraq war certainly showcased the horrors brought on by unnecessary unilateralism, and young people have found Paul a resonant critic of foreign adventure. But working through both I see Pinker's larger trend: in recent decades, every cohort is less invested in aggression than its predecessors, more empathic, less inclined to violence.
