In Ukraine in general, ~68% speak Ukranian natively, ~17% are native Ukranian/Russian bilingual, ~14% are native Russian speakers.

In the Donbas, ~27% Ukrainian native speakers, ~29% bilinguals, ~42% Russian native speakers.

Going by nationality:

~73% of Ukranian nationals natively speak Ukranian.

~18% of Ukranian nationals are bilingual natives.

~9% of Ukranian nationals natively speak Russian.

~4% of Russian nationals natively speak Ukranian.

~14% of Russian nationals are bilingual.

~81% of Russian nationals natively speak Russian.

All these numbers are from 2017.

I think it is safe to say that there are in fact many Ukranians in Ukraine, even many Ukranians in Donbas, at least prior to 2022... due to, you know, the ethnic cleansing undertaken by an occupying foreign national army.

My napkin math on those numbers works out to 53% Russian nationals vs 46% Ukranian nationals in Donbas in 2017.

Using a 53% Russian vs 46% Ukranian proportion to justify mass military force against the Ukranian population in Donbas is roughly the same logic that would conclude it is morally correct to invade Los Angeles and deport everyone who isn't fluent in English, which has similar proportions between English and Spanish.

Ah yes, they are just "confused Russians" who speak a different language because of the ebul West.
