I don't use profanity, and I don't plan to unless I'm called to testify in a court of law and I have to quote someone else who did use profanity. But I don't complain when other people use profanity. It's something I have to learn to put up with from other people. Profanity is something that will never, ever, ever go away.
According to a survey performed by Kraft, 74% of mothers have admitted to swearing in front of their kids at least once. The other 26% probably either had poor short-term memory, had children who were perfect little angels who never did anything wrong (at least not that their parents knew about) or had abnormally high levels of composure (think Morticia Addams or Miss Valerie Frizzle from "The Magic School Bus").
People don't use profanity because they're stupid or because they're lazy or because they have a low vocabulary. Sometimes people use profanity just to try to fit in. Most of the time, people use profanity because they're angry or frustrated.
Using profanity is not a crime. It's protected by the First Amendment of the United States Constitution. If I hear you say profanity directed at me, I won't complain. I won't blame you, I'll blame myself because I was the one you made you mad. If I've pushed you too far, if I've disappointed you so much, if I've treated you so badly, I deserve to hear you use profanity directed at me.
