Saying the truth = lies ? How logic you are....
Not a lot of what you said is based on fact though..
They can never learn it without help from third party, their body never allow it.
This was never stated, nowhere does it say that a uchiha lacks the body to learn SM.
History - none become jinjuriki even they fight along with tailed beast for long time (control it).
Irrelevant, do you know how hard it is to become a perfect jin? Only a few that we know of have done it, & since the
only benefit of having a bijuu inside of you is when it cooperates then why would an uchiha ever resort to that? Genjutsu + summoning contract is a much more viable option & less of a risk.
None become sage on they own without third party.
Have you met every single uchiha in the history of NV? The only uchiha who we've seen gain senjutsu were the one's striving to become the next sage of six paths, which includes gaining ashura's chakra/hashi's dna. None of that means that an uchiha
needs help from a third party in order to learn sage mode though.
Manga stated one brother physical weak with the body but owner of strong ocular.
I'd like the manga scan please, because the manga has only ever told us that indra inherited hagoromo's strong chakra. Just because he has strong chakra doesn't mean his body was weak.
Tell me is there any lies in there ?
Not necessarily lies, but not necessarily based on fact either.
