Am I right in that the primary point of contention is about letting DW dictate magical effects that must be allowed? Just because something is possible in a world connected to Fenspace (and Fenspace was visited by Doug and the Girls; that much is impossible to deny) doesn't mean it's possible in Fenspace. On the other hand (I've clearly been reading too much ponyfic; I almost wrote "other hoof" there), I think Bob is primarily objecting to hard artificial limits on what magic can or cannot do, which position I completely agree with. Because hey, it's Magic. It's not free, it takes real time and effort, but the whole point of magic is that if you have enough strength and cunning, anything is possible.
