::I'm not sure I follow: prima facie, as a rough synonym for self-evident, is used to refer to evidence that is sufficient, if not rebutted, to prove a particular proposition or fact.  How could prima facie or self-evident profanity not count?  Moreover, notwithstanding its connotations, if abbreviations of the denotation motherfucker don't qualify as profanity, I'm not sure what's left that would.  Cheers.
