Justin Bieber. Looking for why people hate him?

Maybe it's because he's such a 'goody two-shoes'. He hasn't done anything wrong, and looks so perfect, and is so accomplished, people have to find something wrong about him. So they say he hasn't hit puberty, or he's gay. They probably do it cause they're insecure about themselves, or they're jealous. I personally don't like him, and that's because of his music and voice, and maybe that's another reason. It's just too high-pitched for my taste, and it seems that he repeats the same lyrics over and over in his songs.
