But that works on both sides. People tried to hide on the railings at the top of the stage in my state when Bieber came here to egg him from above (but were stopped before they got that chance) and that's not very respectful at all...
but, neither is screaming at him that you "love" him and saying you'd kill to be his wife, you know? That's kinda creepy.
But neither side is going to stop hating/adoring him to an excess. It's just the way it goes.
