He tells Revolver: "If you think about the type of sh*t you can talk on the internet anonymously, this would never, ever happen 30 years ago. Think about Justin Bieber.

"I can't name a single Justin Bieber song. I don't really know what his music sounds like. But I'm sure it's not good. He's not writing anything life-changing. But if you Google 'I hate Justin Bieber,' or 'Kill Justin Bieber' - and I did this one time - there's thousands of hits that come up.

"And I read all these comments from anonymous people, some of whom are probably 14-year-old kids. And they're writing stuff like, 'I hope he dies. I wish he'd catch on fire. Someone should murder him.'
