I swear a reasonable amount when I'm just talking, as I guess quite a lot of (most?) people do. Between friends and what-have-you I've got absolutely no problem with it (with the C-word excepted, that just sounds foul), but some people do get offended by it, and that's reason enough to curb it a little. You're not going to prove a social point by offending someone in the street. When I see swearing in arguments and stuff it annoys me because people cloud over their points with over-emotive language (swearing in particular), so whenever you want to be taken seriously you probably shouldn't curse like a mofo. Yes, they are just words, but words convey meaning (duh) so you're probably better off cutting down on swearing however little you do, you'll just sound a little more intelligent. Joe x Quick extra 2p: If you didn't know a swear word was a swear word, you could claim that it was no more offensive than any normal word, but the fact that it is a swear word makes it offensive.
