If 50% of the available listening public DON'T listen, is Stern off the air? Or is he kept on the air by a minority?
I can avoid Howard Stern, I can avoid Internet porn, mostly. The problem, like tv, is that it becomes all pervasive and difficult to avoid. Then I have to start withdrawing from the public square. People are doing that, so all the decisions are being made by people who LIKE crap, and more becomes available.
I think reasonable people can make rules for themselves. That is what government is. I think it is legitimate for people to say, "Porn is available, but not right next to the cash register."
