That anon is cooking, that essay begs the question: what do the source/arc dragons think of the oni? Are they prejudice for the sake of dragonkind or is it mainly dragons from the first realm and those not are slightly more neutral? The Life SD knows Lloyd is the grandson of FSM, what are her thoughts that her EM is part oni? Does the Life arc dragon know/care? Will it affect this uprooting or whatever thing she mentioned? Or will the fact the green ninja was MIA for so long she wouldn't even care about the oni-ness?
I think the Sources don't care about the distinction between mortals as they view them as inherently non-threatening, and unless Source Oni are real, I doubt there'd be reciprocated animosity between Oni and Source Dragon.
HOWEVER I could picture the AD of Life not liking Lloyd's Oni blood, due to their proximity to the mortal world as an Arc. I don't really know if the show is every gonna explore all the Oni stuff atp and I'm too tired to consider the likelihood of it rn lol, but it would be interesting if they DID do anything...
