You understand that a network choosing not to run a TV show is not the same thing as banning the show right? No body is saying that videos of Dukes and Hazard cannot be aired, sold, or that you have to burn all your personal videos.
If a network doesn't want to air a show on their network that is THEIR decision. I don't cry foul just because the latest iteration of Stargate doesn't get picked up or because no one shows Star Trek Voyager reruns anymore. These are businesses being conscientious of what people WANT to watch. It's not a statement about what people can and cannot watch.
The only thing worse than the PC police are the "my rights are being oppressed because some people say happy holidays instead of merry christmas" people. Freedom of speech is not freedom of criticism. Nor is it freedom from contrary views.
