In all honesty, I can't claim to be one of the forum members who doesn't curse much, though I'm careful about the setting. When I'm volunteering in the kitchen of our local Senior Center, no one has yet heard me say that "this f**king dough won't rise."
Because you always use enough yeast?
No, I'm with you. Swearing is fine, but swearing in front of people who are offended by it is just plain uncivil.
I once went to a movie with a couple of friends. Afterward in the lobby, we ran into an acquaintance who was there with her elderly mother. The younger women agreed that we all liked the movie, but the mother said "If only there wasn't so much swearing!" The younger women all looked at each other and said, "What swearing?"
I've always sworn occasionally -- not casually, but when I'm really mad -- in front of my kids (not AT them, but in their hearing), which I know is a huge taboo. Now that my older one swears in pretty much every sentence and my younger one curses when he's angry, I don't feel as bad about it. And no, they are not modeling my behavior (if only they would ever do that, my life would be a million times easier), though I suppose they know my ability to handle a bit of profanity makes them more likely to use it.
