Do you think the Jonas Brothers are a bad role model?

My fourteen year old niece’s favorite band is the Jonas Brothers. I personaly think they are great role models for young teens. She was telling me a mom of one of the fans think otherwise. The lady feels the Jonas Brothers having purity rings and how they talk about going green and everything else they say is bad for her daughter. She says her daughter should make mistakes and grow without being pressured to be like the Jonas Brothers. I will try to look for the link and I’ll post it. How do you feel about it? Do you think they are they bad role models, great models, neither?
