Former Splitter's opinion:

After I had accepted that tWW likely references MM, had accepted that the Aonuma quote didn't mean much, had accepted that OOT's method's of time travel were logically flawed and undecipherable, had decided that the epestemology that spawned the DT was disgusting, had pretty much given any hope on a proof for the DT existing at all, I still beleived in the theory.

Stupid of me? Of course, but it was an emotional thing. I did not beleive that OOT's ending could stand for anything besides absolute victory. And I see the exact same thing in many, many, many timeline newbs. Link must completely defeat ganon at the end of OOT, nothing less is possible, nothing else make sence. Before knowing anything about the Timeline # argument, they will invent crazy, unsportable theories do defend this stance; even when there is nothing to back it in the first place.

IMO, to destroy the Double Timeline, one would have to destory the feeling of accomplishment found at OOT's end. No other logical argument matters, because, at the heart of this, this is not a logical thing.
