If you were teleported back to the year 0 and went to what is now the US and encountered a large ethnically homogeneous tribe, what exactly would that smoke signal to you?

(Editing: as far as "ascribing what you think", the only things I've ascribed to what you think that you think that ethnic homogeneity in post-European white population is morally improper, which is exceedingly clear from the phrasing of the first comment you posted when you called it a "problem", and that you believe your community was racist, which is clear from the second comment you posted.)

"Imagine an absurd hypothetical year zero where no contextual understanding of the history of racism is relevant, then what would you do?"

Sure buddy.

Imagine being so reductive you lost the point along the way

>> Ethnic homogeneity is a smoke signal

The Kenyan soccer team doesn't have any white players. Are they racist?

How on earth do you people think this is some rhetorical slam dunk. You're literally telling all of us who you are. What I want to say to you past that violates the rules of this place, but I'm pretty sure you can get the idea.

"You people". I don't know, but that sounds pretty racist.
