Personally I think you should be able to say whatever you want on the airways and TV, and ratings can decide who succeeds and who fails. Most people don't want to hear and see vulgarity on TV all of the time, so they will tune into stations that take a more polite, family approach. I don't agree with censorship on the airways.
Wikipedia can be biased toward one side. Some of their stuff isn't fact, just opinions presented as such. They can list dates of certain things occurring, which are facts by themselves, but turn around and then mix it in with opinionated information. They are subject to the same criticism as any media source that presents facts mixed with opinion.
