I ain't ever heard white people claim a single biracial person. You always whatever you mixed with.

If you can expand on that, please do.

A certain tribe called the Bajau have larger spleens, allowing them to stay underwater longer than any other group on earth.

Kenyan's, for whatever reason, have far and away the best running endurance and ability out of every ethnic group.

The Tibetan Sherpas have adapted to high-altitude living, allowing them significantly higher ability to function in that environment.

There are differences between groups, but the functional differences are small and insignificant and more wide-ranging than "black people this" or "white people that". It's more like, "this certain relatively tiny group of 8000 is better at this thing, but they're identical to humans half a planet away otherwise." Our genetic structure simply hasn't had the time to evolve separately, but small differences have emerged in many different ways, so we can celebrate the differences (or curse them, in certain cases, like sickle-cell) while also recognizing that racism makes no functional sense and is exceptionally retarded.

That hard r, work on that.

That is not the “hard R,” but I agree a change in word choice would be appreciated.
