what is obscene and not is not universally agreed.

For example. some normal word in my country is a ofensive word in another country (that speak the same language). Then the real question is: What is a obscene word?

aha, the battle between modernists and traditionalists )) ^__^ I VOTE FOR FREEDOM OF EXPRESSION !!! ^__^ obscene words transform into simply vulgar it is natural to use them sometimes ^__^ I VOTE FOR FREEDOM OF EXPRESSION !!! ^__^ if I want to say that Hitler is a motherfucking bitch, I do say that!!!
