Why do you dislike/hate justin bieber?

i don't like him because he is like 18 years old but has the voice of and looks like an 8 year old. He also thinks he is cool because of his singing. i mean do you see his style? flat cap tilted to the side. skinny jeans with high tops? So many people did that before him but people say that he made up that style and everyone else is copying him.
