I was getting ready to watch the trailer for the documentary Countdown to Zero a few minutes ago, when I was struck by the standard Motion Picture Association of America advisory statement at the beginning. The preview had been approved for “Appropriate Audiences” only.

The documentary is about a call for a worldwide nuclear disarmament. The Motion Picture Association of America didn’t think that message ought to be seen by children.
Why not? There was no nudity or profanity.
And so what if there was? What kind of world is this in which we censor previews of documentaries about nuclear weapons from the eyes of children, but our own government won’t promise not to detonate those nuclear weapons in cities filled with children?
Postscript: YouTube says that the video most related to the Countdown to Zero trailer is the trailer for the horror movie I Spit On Your Grave.
