Wow, thanks for the link. I thought that song was AWESOME! It's great that people can express themselves in different ways. As far as what you say about exploitation, I don't see that at all. I don't understand why you said that. I think this song was great, thank you for posting this link.
I think locking up teens for no reason is exploitative. This is kids who were harmed expressing themselves in a healthy and, in my opinion, quite beautiful way.
