I was thinking the same thing when I saw that leave justin alone video on another thread. The death threats and websites seemed a bit extreme.
If you dont like someone, you can ignore with them. You will come across them from time to time. Grow up and deal with it.
But actively commenting on videos and making websites is weird. Youd have to be a very sad person to devote your time to something you hate.
Personally, i have no problem with Justin Bieber. God, when I look at the kind of crap I used to listen to when I was younger, i cant really talk.
