Nick Gillespie:

there's no question that over the past decade or so, kids have been exposed to far more sexual content than they used to be, on the tube and elsewhere. What's more, everyone will agree that most of this content is presented in glamorous fashion. Yet this has not created a generation of sex-crazed adolescents....Similarly unrelated trends also hold for violent TV and youth crime: as the former has increased, the latter has declined.

It's always made sense to me that that art isn't all that good at "sending messages", no matter what the politicized critics argue.
