I love to see people standing up for virtue in all of its forms. NPR just did a story about Mckay Hatch, a 15 year-old boy from Pasadena, California, who started a "No Cussing Club" with his friends at school. He also posted his own rap video on Youtube, has grown his club to 30,000 members through his website, and has a book due out soon.
Mormons are discouraged from using profanity, which includes irreverent reference to any member of the Godhead. The standards for language outlined in "For The Strength of Youth" instructs us to, "Use language that uplifts, encourages, and compliments others. Do not insult others or put them down, even in joking. Speak kindly and positively about others so you can fulfill the Lord's commandment to love one another. When you use good language, you invite the Spirit to be with you."
