Adolescents tend to be passionate people, and passion is no less real because it is directed toward a hot-rod, a commercialized popular singer, or the leader of a black-jacketed gang.
I don't understand why we have laws that prevent someone from walking a school campus and selling alcohol or drugs but somehow can't feed our children who attend those schools a healthy balanced diet, which I think is a lot worse. It's offensive and I think anyone who isn't offended by it is an idiot.
