I remember when Will Smith won a Grammy award, he claimed he succeeded without swearing at all. He meant it as an insult toward the rappers who did. In "The Real Slim Shady", Eminem had a curse-laden reply to that. Another time, Eminem exclaimed his stance on the matter, and I think what he said is appropriate - I respect your right to an opinion, but not everyone is as happy as you are. Everything isn't bees and flowers, and sometimes the right situation calls for that added oomph.
