They shouldn't be censored, but they should voluntarily give it up as an act of dignity. Unfortunately, most of them have none. Shows that openly purport to entertain only are subject to looser ethical constraints, but those that claim to be serious are a lot more dangerous. Too many of the shows feature white supremacists, black racists, and a host of other groups who are constantly at work dividing our society. This is the breeding ground for cultural dissonance.
Nothing is accomplished except hateful bickering.
I'm sure there will soon be a mass of research among sociologists and psychologists devoted to understanding why other people's problems are of such fascination to us. College students of the future will be asked to study this research. But I don't know if it takes a social scientist to analyze the problem. It's called vicarious experience. It allows us to step into someone else's shoes for little while and immerse ourselves into their lives.
