Why make fun of Justin Bieber?

He's just a teenage boy, following his dream. If you were living your dream at his age I'd look up to you. I guess not everyone feels the same way.
The way I figure it, people are jealous that Justin Bieber has acheived so much in so little time. You can disagree with me, but I honestly believe that's the reason a lot of people hate him.

If you hate him ,tell me why in comments, because I really don't get it.
