Not a lot of what you said is based on fact though..
This was never stated, nowhere does it say that a uchiha lacks the body to learn SM.
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.
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.
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.
Not necessarily lies, but not necessarily based on fact either.
Yea just because you ignored the fact that something never happens and it was a reason behind it. Let me tell you a tale, naruto will kill sasuke and take sakura as second wife in the future. In the past madara constantly rape obito when he need to this is why he become child molest later.......all of this possible happens cause i feel it too. Is that right ?
