Listener, that is a false comparison. Jesus was depicted as the "Son of God". Besides, as far as the Gospels are concerned, he did not make a "habit" of turning up to throw out the moneychangers. He made his point and moved on. Some of these protesters regularly turn up at the JW memorials - although they may choose different kingdom halls or locations.
Say what you like about the JWs, if they were doing something egregious in their meetings, I'd have a greater understanding of protesters; but "simply" conducting the evening meeting to their view of the memorial hardly constitutes justification for making a scene.
