Yeah, but that's mostly a thing that reverts to the mean, or at least did in the past. When everyone is mostly living in their own racial groups, you get the one or two guys and gals who want to mix (AND have the opportunity AND aren't swayed by the much stronger social pressure against race mixing and so on), they have some mixed race kids and that one mixed race family lives with a bunch of other families that aren't mixed. Then over the generations, it dilutes. So the first generation is half-American Indian, half-American White. But they're living primarily with a bunch of American Whites around them, so the next generation is 25% Indian and 75% White and so on until you get down to someone like Elizabeth Warren who claims to be Indian and then turns out to be something absurdly small like 1/1052.
Of course, in modernity those geographic barriers and social barriers are both lessened, so we see a lot more race mixing and it's less likely to revert to the mean over time.
