Censorship?

Ok, strangest thing just happened. I had ABC on, and "A Beautiful Mind" was about to come on when they put up a warning, like one of those "viewer discretion is advised" things. But this one said: "Due to current sensitivities and adult content, viewer discretion is advised."

Ok, first off, I have no idea what adult content there is in this movie. I saw it. Didn't seem very violent or sexual. Second, what the hell are "current sensitivities"? That must be a euphemism for the war in Iraq, but what the hell does that have to do with "A Beautiful Mind"? I am completely confused. Anyone?
