Well, let me state some things before we jump onto conclusions with that haste...
Statement a)
You don't know Madara's full potential. But let's say that the current Madara is at its full... he hasn't shown his trump card. You're assuming too much things at this point.
Could you explain how a Mother can be stronger than a Son that absorbed a
God inside? Did you stop to think that it was her son the one who revealed the secrets of chakra and ninjutsu and not her?
So I'll answer straight but subtle, as a true gentleman... Yes, I don't understand the manga logic at its fullest, but neither you do... because you lack definite proof to support your statements. From my part, I only state something as fact when I have proof to back it up, and I accept my defeat when people presents me definite proof against my statements. That's how life works.
Statement b)
As I said in a), there is a chance that my logic can't be fully applied to Naruto.
Statement c)

Fail comment, I have backup to prove that my theories led me to think otherwise. This is my proof to break your statement. I didn't think about the Sage as Uzumaki, my belief lend me to think that he was the Ancestor.
Albeit, my own statements were wrong, because I too was too naive to present solid backup for these statements... the only thing that was right was my own hunch, that the Sage was the ancestor of these clans.
--- This told, I'll thank you if you restraint yourself next time to neg rep me. I won't do the same damage you you, since as I said earlier... I'm a gentleman.
