I've always liked what my 8th grade English teacher said, "Your choice of language use is one of the first and most powerful impressions you leave on a another person. You can choose to sound smart and articulate or course and brash. Choose wisely."
If you can't express yourself without dropping a word that someone else is likely to be offended by then perhaps you have to look at what it is that you're trying to say.
