I have been reading this the top 2 thread since last Sunday and what occurred to me is.
1. Lots of people dont have discussions with each other. Is more arguingwho tobi is and then get annoyed or even pissed-off.
2. There are allot of different theories (some based on a few assumptions and other on facts and logic.
3 What I also find is that the most Tobi=Obito theories are based on very little Manga facts, timeline facts,logic and what tobi said in the manga.
For example: A member does a really great job to type a massive explanation about that tobi = izuna. And the Obito theorists reply ''Well tobi lies about everything, or He doesn't want naruto-verse to know that he is Obito and the so called proof that Tobi = Obito is that he has is eye and that He knows mutch about Kakashi etc.''
But when a Tobi=Obito theorist wants to proof that he is Obito. The post is very small, Few facts, 1.000.000 assumptions. And lots of rage, anger, and denial and then tobi = Izuna Theorists reply with another Big explanation.
And for the sake of argue, I dont have a theory of my one, I like to read other people's theory and follow the ones who makes the most sense.
I think when it comes to reading others people theories you most read it objectively. And when it comes to making one you most go far back into the story and take out the facts as far as we know, fill in the plot-holes with plausible explanation what fitts in the naruto-verse story. Timelines are a big help.
Dont be hating because I dont hate either. When I read a very stupid theory I wont even comment on that members Theory. Only in general.
