[Natural Law]

"Of course neither Greg or Darwin lived long enough to see this eugenic Utopia come to fruition but they certainly would've had no difficulty understanding it and its roots"

Any nation or culture with a history of monarchy, oligarchy and colonization was well versed in "Natural Selection" as it applied to human populations. This dates back thousands of years and is not limited to Britain or Europe. To try to link Mao's cultural purges and the Holocaust to Charles Darwin is simply specious.

The evidence is the evidence even if you don't like it and saying “specious” doesn't change it.

But as to these nations “well versed in Natural Selection”, whom might they be?
I understand many people had some notion of evolving over time or something like it but “Natural Selection”?
