I don’t know anything about the kid except that he’s some big deal with the teens.
But really, he was just a kid going to a basketball game. Unless he tried to attract attention to himself, I think the booing was uncalled for.
Hating on Bieber has become a cultural phenomenon. You can’t go to a video for a great song on YouTube without seeing in the comments, “F Bieber! THIS is real music!” Others say, “Who cares about Bieber! Just enjoy the song!” I’m with them. If the kid has connected with a certain segment of the market, good for him. He seems to be a Christian, which is nice, and I can and do choose to ignore his music, myself.
