why do people go so mental at justin bieber?

[Claire P]

Because it is mostly the pre teen - teenage girls who go after him, and they're in that stage of life where their hormones are jumping around everywhere, making them feel like they need boys-- especially when they see someone they think is hot (Bieber). I definately don't see the hotness in him. He looks like he's 10 to me. I'm 16, I wouldn't want to date someone who looks 10. Anywho, they're just letting their insides control them so they scream and do everything they can to see/touch Bieber. And they think that someday they'll be married to him, but don't understand that millions of other girls think the same.

Plus, their parents probably didn't teach them much about how to act around someone you like. If I was a guy, and a girl was screaming for me or trying to get into my room, I'd never want to see them again. And again, they're young, so if you tell them anything they won't listen.
