Well I remember a lot of the opposite conclusion: "swearing is good for you". Just Google for it, there's lots of entries. Reading the OP's list, "to fit in", "to stick out" ... this doesn't apply at all to the very common situation of swearing when all alone. I personally swear and curse a lot in the privacy of my home using horrible constructs in a language way more expressive than English in this regard. English has like what? Funk and consarn it? Swearing makes me feel better over situations I've little control otherwise.
