At 19 I was a blithering idiot. Now I'm too old to blither but I'm still holding up pretty good as an idiot. The thing is that teenage male brains mature at vastly different rates and stages. Some 19 years olds might be quite responsible and capable of good judgment, others not so much. I'm not at all interested in Beiber's music but it's interesting to consider just how completely out of the norm his life has been. With his fame, wealth and opportunities he has almost no peers. Who does this kid look to as a role model? How can he identify with the choices made by older or more mature males? Nothing in his family background prepared him for the world he occupies...how could it?
I'm not defending him and not making excuses for him, It's just that his world is radically different from other kids. The same kind of madness hits young sports stars. They have no preparation for their "stardom". What kid their age do they have to compare notes with. The examples most of these young guys have come from the sensationalist media that preys on their fame and behavior because they make good press.
As far as the fat bumblefuck, hide the bastard someplace so the media shuts up. The quicker he lands in prison the better for all of us. He bores me.
