Just call them Nons:
The non-white races go by many different names and terminologies, some specific, some general.
Unique terms denoting a plethora of different and specific non-white: ethnic groups, races, linguistic groups, and even a wide varying of mixes amongst themselves and even with Whites.

This becomes overly convoluted when discussing non-whites in general, when we don't care about their uniqueness, preserving their specific groups, etc. We only care that they stay separate from Whites, that's it; they can mix into a million different shades of brown amongst themselves and we don't care; so why even mention specifics?

Clearly the perfect term for them is non-white, denoting them as specifically not us; however I find it's disgusting to damage the purity and integrity of the word White by suffixing it to non-White, so drop the suffix and call them Nons.

I'll make it clear that you're a Non if you are not 100% White (West Eurasian), a drop below and you're a Non. To clarify further, admixture from the ancient ethnic groups Natufians, and West Siberians, are found in varying degrees in Southern and Eastern Europe, respectively.

Modern geneticists will claim these ancient Caucasian groups were negros and orientals, respectively; but this is politically motivated and baseless beyond the errors of K-Means Clustering which group by similarity, rather than descent (what actually makes a race); a similarity which is likely caused by Natufian/ West Siberian admixture in the adjacent Non races, rather than the inverse.

To reiterate:
They're non-White.
They're non-Adamic.
They're non-human.
Just call them Nons.
