Principles of Right and Wrong in the Society Today

I think that today we are a lot more tolerant than what people used to be. Now days their are more shows that are less discrete about what they show on it. They show more sexual scenes, and foul language. Desperate Housewives is a really good example of a show that shows way to much for a certain age. It pretty much revolves around sex and foul language. When my mom was a kid she said she never saw shows like this. The shows that used to be the X rated  shows are now the PG13 movies. If this is what the world is like now, what can we expect the future to be like?
