"This polarization of the issues has contributed greatly to our national paralysis, because it posits false choices which stifle debate essential to change. It is ironic that this should happen in a time of great social upheaval, when our society needs more than ever to be able to experiment with different viewpoints. But in the media world, a previously established idea, like a previously elected politician, enjoys a tremendous advantage over any challenger. Hence the familiar ideas continue to be repeated, long past their demonstrable validity."
