As far as I'm aware, though, there isn't any age restriction for the main tent, and besides, "Bad Parenting" is no excuse to take out small children, be they hypothetical or not. :-) Having said that, it was probably a bad example. My main beef is with people who don't give a damn if they screw up the festival for others as long as they're enjoying themselves. For example, why have the water-balloon cannon in the first place, if not to target people?
