cursing, imo, is using sharp, powerful, ugly, disturbing, edgy, expressive words to show sharp, powerful, ugly, disturbing, edgy feelings. nobody ever (well, not usually) means what the word's literal meaning suggests. In one word you've said more than any paragraph could say. throwing cuss words into sentences gratuitously is wasteful, but no more or less than, "like", "y'know" and other unconsciously added stuff. So either way, they aren't sinning, to me, because their intended meaning, as said, has little to do with their literal meaning. They are a sub-set of language with a whole different meaning for these words, determined by the speaker (thus, freedom), context (thus, communal meaning), and other factors. I think cussing is underrated.
