I see nothing wrong with vulgarity or profanity so long as it is done at the appropriate time. Entertainment is one of those times in my eyes because you have the option to watch or not watch. Inappropriate times are work, school or places of public accommodation, and I mean this from the standpoint of good manners, not from the standpoint of government intervention. Government should never step in to prevent "vulgarity".

When I am with friends and family, I swear quite often, however I have never done it at work. For it is only a form of expression and should not be given too much import.
