TBH that's one reason I brought fanboyism -- or should I say,
Fan Dumb -- into it. I see people doing the same every day without even having the divine inspiration excuse.
Basically, fan X doesn't like that his favourite comic, or anime series, or movie, or computer game or whatever says or portrays a trait or event Y. Maybe it doesn't fit his idealized, and invariably wrong, idea of what it really portrays or should portray. E.g., maybe people remain unconvinced when he insists that a comic created in the 50's is about the USA justifying their invasion of Iraq some half a century later. Or maybe he feels that other people don't have the appreciation he expects them to have for the character that he's worshiping. E.g., that character was given enough anti-hero traits to make him almost indistinguishable morally from the villain, in a grey-vs-grey setting, and people keep pointing out those flaws or *gasp* actually pointing out that it's grey-vs-grey and not one knight in shiny armour vs the incarnation of all evil, instead of being just as awe-struck by that character's awesomeness as he is. Etc.
So, anyway, the canon says Y and fanboy X doesn't like that one bit. So he proceeds to start ten threads to argue why Y never happened. Or it really means Z. Or that prior events A, B and C that he just pulled out of the butt, totally change Y or its moral aspects into something completely different.
As far as I can tell, the only checking against "reality" happening for these guys is that if Z is more palatable to them, it must be true.
And you can really find examples in any domain, from novels to movies to comics to computer games. The less important it is for anyone else whether Bowser is really the villain or a misunderstood hero of the old 8-bit Mario games, the more effort someone out there will put into making sue everyone understands that Bowser is the hero.
I suppose that, yeah, some of them WOULD claim divine inspiration if they could.
But really, I'm not the impression that atonement or attuning with a higher power is the actual motivation. Someone is just obsessing over some fiction character or series, and is going to invent anything it takes to make that character closer to their idealized image, or respectively to sell that fanboyism to others.
But at any rate, it doesn't make the idea that someone thinks he can just invent reality, or that whatever he likes more somehow becomes more real, any less scary.
