[Garen LiLorian]

Although everything you've said is reasonable, I remain unconvinced. There are several times when the people in question call what they are doing magic. Like, for example, the dwarf song in the hobbit; The Dwarves of yore made mighty spells, and Gandalf puts 'a shutting spell' (in his own words) on the door in Moria, and says at the west-gate of Moria 'I once knew every spell in all the tongues of Elves or Men or Orcs, that was ever used for such a purpose.'

Now, it seems fairly reasonable that, whether magic consists of just knowing something extra, or actual spells (although, I don't really see the difference) if the person doing the spell calls it magic, than so can we.
