I had a close friend who was a master at turning people's behavior around. Instead of having these folks whisper behind your back, turn the tables on them. Go to the scoutmaster and those who are "gossiping" and ask for their help and advice as to how they would handle your son's behavior. First, it will let them know that you are fully aware of their snide comments. Second, it will shock the crap outta them . third, it gives them nowhere to go with the gossip. Involve them. You just might be surprised at the change in their behavior. good luck!
