What I think it is, is all the kids hate Justin Bieber and try to show that off to everyone so they (think) they seem all badass or whatever but they end up being just as annoying. I mean, to be honest I dont like Justin Bieber as well because of the amounts of publicity he receives, but I can recognize he has some talent singing.
To be honest I think the reason most people hate Justin Bieber or The Jonas Brothers is made out of jealousy, I mean lets be honest, who wouldnt want all that attention from girls and loads of money?
