I do agree that swearing has gotten a little out of hand from time to time, though I don't see any reason to stop people because its their choice to swear or not. I myself swear but only when I'm really pissed off but other than that I almost never swear outside of that kind of situation. I do find it annoying though when your talking with someone and every sentence has a F***, Sh**, etc in it.
Honestly, I couldn't care less about people swearing, although I myself try to keep it to a minimum (you can't always tell though).
