I agree that there is some sort of genetic taint on mixed-race Latin Americans.
But also consider that about one-third of Latin Americans are white. I divide the population of these countries into two classes: “Spaniards” and another word beginning with “s” that I don’t think I’d be allowed to use here.
Just read about the Aztec practice of human sacrifice. These Native American cultures were violent to the core.
The Cubans I grew up with back in the 1970s were for the most part obviously of either pure Spanish descent or so lightly mixed as not to matter. We had no problems with them at my high school in Miami — they were first generation Americans, most of us were second generation, mainly Italian and Jewish from New York.
Mexicans, on the other hand, are the inheritors of one of the sickest cultures in human history.
“But the Aztecs built and empire. And their architecture was magnificent — just look at those pyramids.”
The problem is what happened on those pyramids.
A friend of mine was stationed in Panama in the early sixties. He used to regale us with stories of his adventures in the region, and the gruesome, unspeakable violence he witnessed there among the native peoples. We were mesmerize by his tales, long before America had been invaded by MS13.
