Technically, you can have resistance to varying types of magic in the game, from a mechanical standpoint. If you look at your Attributes tab for your character, there's an entire section on elemental resistances - something that is very faintly altered by which Guardian you chose, if I recall correctly. That or your race. In addition, you can meld elemental materia to your gear to further increase your resistance to a particular element and there are elemental resistance potions.
So, as such, it wouldn't be too much of a stretch to assume that a character could have natural resistances - or have built them up like some manner of immunity (though I'm less certain on the latter; I don't think you'd get more resistant to Flares just by letting yourself be hit with Fire Magic over and over again). And, I would postulate that fire magic is indeed different than normal fire, just as arcane levin is different than normal lightning. It is merely individuals adapting their personal aether to something on the elemental wheel and projecting that.
... Or something like that. Also, you don't need to have duplicates of this thread in two different sections.
