Racial simplification is a bunch of crap anyways.
If you research European history you will find a large percentage of Europeans are mixed with 'black' African, middle eastern (themselves a big mix), and Asian ancestry.
From all the mixing during trade and various wars.
Notable large incidents including mixing with the hordes of Ghengis Khan,
Take a look at ancient paintaings and sculptures of Romans and Greeks, nothing like Romans and Greeks today. From color, to bone structure to hair, the genetics are very different.
This goes back to Roman slave days, the Romans were racist, and wouldn't mix with others originally, but in later times mixed with most of their slaves.
They then mixed with various cultures and armies that conquered the region over time, as well as through trade.
The French or Gaul was predominantly fair skin and hair, Celtic.
Hispania or modern Spain was much the same.
Looking more Nordic than they do today.
Yet today are predominantly black haired people of many complexions.
This goes back to the Moorish conquest, when people of black African and Arabs ruled over and mixed with modern day Spain, and France.
Before modern times wars tended to mix populations a lot more too.
From marriages, to rape and prostitution, most nations at war with armies that marched over long distances and 'lived off the land' (raped and pillaged) mixed genes.
Most of Africa was colonized, their genes have a large percentage of European ancestry since now, even if they are quite 'black' in skin color.
Just as most US blacks today, many of whom have European bone structure and are more European than African, yet are 'black' or 'African American'.
And that does not even touch the surface.
My point is that 'white' is already meaningless.
Black is relatively meaningless.
And if you go south of the border, the mixture is so massive, it is hard to even categorize.
Mexico was the melting pot long before the USA. From the large number of Natives, to the massive importation of African slaves, to often unrealized but large immigration of Asian immigrants. On top of the Spanish blood.
They call it 'Mestizo' to be mixed, and most of the population is mestizo.
Most who don't think they are just don't know enough of their history to go back far enough.
Genetics play a very large role in many things, but they are so much more complex than the simplification of 'race' as it is known in the US.
Most people don't really want to hear the truth though.
