From the link:
"We the people of the United States feel that we are being wrongly represented in the world of pop culture," says the petition, created by one "J.A." in Detroit on January 23, the day Bieber was busted in Miami Beach for impaired driving and illegal drag racing in a flashy Italian sports car.
"We would like to see the dangerous, reckless, destructive and drug-abusing Justin Bieber deported and his green card revoked. He is not only threatening the safety of our people but he is also a terrible influence on our nation's youth. We the people would like to remove Justin Bieber from our society."
Based solely on that wording then a similar petition should be drafted for a lot of Hollywood elites (Lindsey Lohan, Charlie Sheen etc) as well as most rap singers. While they cannot be deported as they are americans I still think they should be removed from society. They could call it boarding the Bieber bus.
