Not a physical assault, certainly, any more than a flasher in a concert hall can be said physically to have attacked his audience. But not just aesthetic, or metaphorical, either. The first time you go to a concert, and there is a flasher, that is one sort of event. If, on subsequent occasions, there are variants of the flasher, and you become aware that the flasher is part of the program, then it is the notion not just of the concert, but of you as the concertgoer that has changed. You either annul your subscription, or you consent to be described in a new way.
