Censorship on TV

[Reef]

I don't post much here, so please bear with me. I was channel surfing and landed on Frasier last night at 7pm. Soon afterwards, I heard a character say "b!tch". I'm 21 years old and am not easily offended, however, I'd hate to have my little sisters (both under 11) to hear this on TV since they watch so much of it. I'm sure most parents feel the same way I think there should be a few words censored from TV.

I'd like to hear the forum's opinion on this
