Someone left a comment about how, if I don't want my kid swearing, why do I use profanity all the time? And I've got nothing else to blog about, so you're now stuck reading my Theory of Profanity.
I don't want my kid using profanity for the same reason I don't want her using a paring knife: she's not old enough to understand how to use it, yet.
I'm a writer, and a former English major. (There's no such thing as a former English major. It's like the Marines. Once joined, always a member. Except instead of "Semper Fi" it's "Carpe Diem".) For most writers, there's no such thing as a 'bad' word. Some are just, well, stronger than others. Living in Hawaii reinforced this a great deal; Hawaiian has no profanity, and the concept that profanity is about usage and tone of voice has washed over into all the other languages out there. So when used properly (like, say, to express my opinion at the idea of a 38" bust equaling size extra large) it just underlines my point, or adds humor, and whatever.
Until my kid gets better at gauging social situations,the idea is for her not to swear. In fact, she's heard ALL THE WORDS, and occasionally uses them. Sometimes her stuffies or Little People get angry and cuss each other out. If she's alone in her room at the time, I don't say anything because it's an acceptable use. She's JUST starting to understand "home manners" vs. "out in public manners", and once she really gets it, I'll loosen up a lot on the occasional swear word. As it is, she will occasionally mutter "what the hell?" and again, since it seems appropriate (like when seeing High School Musical), I let it ride.
As for my language, these days I mostly swear on the internet, due to that kid thing I've been discussing. Usually for humor, sometimes for emphasis. Because it's the internet, people are able to decide for themselves if they want to deal with it and not read if they don't like it. Simple enough.
