What do you mean by 'societal definition,' how does it differ from the dictionary definition? It's not like the people who write dictionaries are ivory tower intellectuals, transcribing esoteric knowledge while being totally disconnected from society. They base their definitions on the linguistic use of these words in modern times, so that they hold practical value in situations like this.
And I'm sorry for being a "pedant," but it's kind of necessary to define a term before discussing whether something meets the definition of it. Saying that you all know some vague 'societal definition' doesn't make what you're doing any less arbitrary. Suppose you declare that the letter in this case isn't vulgar -- what then? All you're doing is muddying the definition of the word, confusing everyone involved and leaving everyone else in the dark. It's not like many players will actually read this thread and come to the understanding that BM's definition of 'vulgar' is narrow, obtuse and largely unrelated to any other.
If you want to have a special definition for the word, that's your prerogative. But if you want people to understand what you mean, you're going to have to add a note in italics underneath it, explaining what you really mean. Simply brushing it aside on a forum, which most people don't frequent, is totally impractical.
