I don't know how I feel about it, and I haven't listened to the recordings from the concert. I don't think what we as foreign fans do in the context of this forum ever really radiates out to her entire fanbase so there's not much of a chance for it to reflect badly on us as a whole? As long as it was done discreetly no one else at the venue knew anything about it.
But when you're doing something to cause a scene and interacting with security, THAT is a problem.
