On the one hand, there are several legitimate questions that can be phrased in this manner. Off the top of my head, there are several already on board, regarding aliens, vampires, werewolves, time travel, babies being born without teeth, Migdal Bavel, the elements, graphology... The list goes on and on.
But that the list goes on and on is precisely the problem. At what point do we draw the line of what sort of question is on-topic and what sort of question should be "taken out and taught outside"?
