Entirely possible race-wise. My former Mexican landlords here in Hollywood can EASILY pass as Irish. People dont know there are 2 kinds of Mexicans, the aztecas (dark) and the mestizos (white). The mestizos were direct descendants of the Spaniards. There were countless times the couple were being invited for St paddy’s Day and they have to explain countless times they were originally from Cabo.
That doesn't match my exposure, in Mexico, New Mexico and south Florida. Indios or aztecas are the dark people of smaller stature, at the bottom of their pecking order. They are the inhabitants who greeted the Spaniards.
In between are the strivers, not quite sure whether to claim to be white or indigenous, and claim either when it's advantageous to do so. These are the mestizos, literally mixed race people, white and indio.
At the top of the heap, in Mexico, New Mexico, south Florida, Cuba before Castro, any Hispanic culture or nation really, are the Castillians. They're as white as any European and in fact are descended from nothing but. Spain is a European country, Spanish is a European language and the people who fanned out from there to conquer various continents and peoples were European.
It's really all quite "racist" by any standard, and to hear such people claim racial victimhood is peculiar beyond words. But, it's what our pop culture media have foisted upon us, and they do capitalize upon it. It's all about what they can get, and we're dumbed down enough to swallow it, hook line and sinker.
