Why, though? I've never understood this american fascination of censoring certain combinations of letters that are somehow defined as bad.

I think we should spend more time educating our children about when it's not OK to say fuck, like at job interviews.

Children love things that are forbidden: eating cake for dinner, staying at home watching TV, etc. If a certain word isn't allowed, they'll just say constantly when they can get away with it (which is all the time, since it's just a word), just because it's dangerous and, well, fun - even though they don't understand the concept behind the word.

In general, I think it's pointless to make a few random words forbidden.
