Explanation on the R=U theory?

[Lilliputian Hitcher]

Lilliputian Hitcher gave a pretty fair account of what is wrong with the theory, although a few things I would consider important were left out or glossed over. The most important of which in my opinion being Griever. Frankly I just don't like the most common explanation for the anti- R=U stance, that being that he is created to intimidate Squall. I remember hearing that the Japanese text actually confirmed this, but even so I still think its a bit stupid.
The Ultimania guide does cause massive problems for the theory. Rather than try and work around them, if I were to try and support the theory, I think personally I would reject the guide as part of the story, even if it is officially canon.

I would personally advise against this. Not including plot points that have been considered canon for the sake of a theory would be like disregarding Squall's gender in order to prove that he was really Celes. Ultimately theories that go against canon are a waste of time since:

1. They can't possibly have been the intentions of the original writers, since it refutes they official material and;

2. No one would take the theory seriously.

Changing game facts is fine for fanfiction, but game theories have to actually work along side what has already been considered canon; not work against it.
