It would be difficult to find anyone in media history as evil and destructive as Don Hewitt and his propaganda creation 60 Minutes.
I agree with your thinking but Norman Lear has easily been as destructive as Hewitt. "All in the Family" and "Maude" stereotyped, distorted and ridiculed conservatives and conservative ideas and even promoted abortion. His advocacy group People for the American Way is Marxist and should be re-named People for the Socialist Way. Maybe worst of all, he unleashed Rob Reiner as a media/political activist, LOL. It's hard to think of a far-Left idea Lear hasn't promoted while disguising himself as a strict Constitutionalist.
