Is it really that great of a feeling to pick on a teenager that made a wrong choice in her life? I mean, honestly, who didn't want to do a retarded thing when he/she was 15? The only difference is we were couldn't and/or where stopped.
She didn't have somebody to stop her, or even worse, she had somebody who encouraged her to create what can be described, at best, as a mediocre song. She's not the real monster, the people who promoted her are. This kid might end up with serious psychological issues because of this song and the general opinion it got.
Also, saying the song is bullshit is debatable. As shitty as it may be, she's probably made millions of bucks while we're on a forum talking about her video. Somehow I think the roles here aren't that clear.
