Your reasoning being absolute and mine being invalid by your admission is ridiculous to be honest. I simply stated that kushina had whole kurama right? She was Jin to whole kurama because of her uzumaki heritage and in effect it's connections to the senju(in this particular case, life force and chakra) if Minato had any such connections why would he struggle to seal even HALF of kurama with an uzumaki seal? Cmon dude you can't conclude he WAS a senju based on assumptions.
And honestly at this point I've used more manga references to say he isn't a senju then your simple he's like tobirama he must be a senju reasoning
I debunked every one of your assumptions, unlike you.
Again, being Senju doesn't mean you are able to seal a beast in your body.
Some Uzumaki have the power to do so, not Senju, making your point invalid.Why Tsunade isn't a jin?Because she doesn't know the Uzumaki jutsu to do so, making again your point invalid.
Senju are not known for their life force, Uzumaki are.
I never conclude that Minato was a Senju.Unlike you, I'm not stupid enough to claim hypothesis.
If I'm not mistaken, Kaguya is only related to Oktsuki, Hyuga, Senju, Uchiha, and Uzumaki. Other clans may have mixed with these clans over time, which may explain blood line limits. Although people were still living on the planet when kaguya landed/arrived, and when chakra was distributed everyone got chakra.
At bold: Ashura's step-brother? or Ashura's step-father? Wouldn't these people not be blood related then?
I don't like this idea that every ninja clan comes from Kaguya.
Ashura's step father/brother has no relation to Ashura, but the sons of Ashura would have some of his genes, given that they also come from Ashura's wife who has a direct blood relation to her brother/father, making the descendants of her father/brother distant blood related to her sons who are the sons of Ashura (the Senju clan).
If Ashura's step brother/father created the Uzumaki clan, this clan would be related to the Senju clan.
