The whole ninja dancing thing is kinda annoying, especially when you are trying to just watch the band and you get flailed on by some jerk. I do respect their right to do as they wish, but keep it away from me, or someone is gonna get pummeled. To me, it seems like most of the time, these people do it simply for attention and not out of support or enjoyment of the music. Since its something you mostly do on your own (as opposed to moshing), it distracts from the bands performance and doesn't add much to the show. But maybe thats just the cynicism talking
