I use profanities to help me properly and adequately display my emotions, be it happy or sad. There's nothing a few, well-placed "f*cks" can't cure. By swearing my way through tough situations, I'm less inclined to act out in other ways. Like violent ways. I think that's a big lesson for kids. They should be able to express their feelings in cathartic, productive ways. And if profanity helps them get there, so be it.
