I don't think that using profanity tends to be wrong. (Maybe if, "Damn it!!!" were the vocal trigger for some terrible weapon that could destroy the Earth...) It can’t be the sound of the profane expression that makes it wrong—else "c**k" would be a sin to say even if used to refer to a certain aviary kind. And it can’t be the meaning: to say "sex" is not in itself unethical. What about a combination of a given sound and a given meaning, an emergent (supervenient) property of this combination? It could be argued that to use a certain word as slang for something aggressive or sexual is wrong. But how? If I said "door" to mean the same as "damn" (as in, “Damn it!”), would this be transgression? Here we run into a problem of differentiating between the supposed permissibility of saying, say, “What the heck…” instead of, “What the hell…” or, “What the f**k…” Why is the first generally regarded as acceptable yet the next two are taken to be increasingly unethical (in some circumstances)? It doesn't make sense to me. Is the widespread belief that profanity is, well, profane anything more than some kind of prejudice?
