Mesoamerica’s Amerindians from the Olmecs to the Aztecs (2,500 b.c.e. to 1521 c.e.) were true bastards: a culture of serial killers even of their own children—see the middle of my book Day of Wrath.
When the silly Spaniards arrived in the 16th century—the least racially conscious among Europeans—the first thing they did was cross-breed with these serial killers, completely ruining their culture and genes for posterity.
The Mexican War of Independence against Spain fought by the traitorous Criollos, the Mestizos, the Indians and the Mulattoes (1810-1821) was a war against the peninsular whites. And the Mexican Revolution one hundred years later (1910-1917, although political violence continued until 1924) lowered racial taboos and fostered the rise of non-Criollos.
Today’s Mexicans have internalised the current neochristian narrative (feminism, antiracism, LGBT, idealisation of pre-Columbian Mexico, etc.) with such violence that, in the whole Mexican media, there is no equivalent of a Tucker Carlson who speaks with some measure about a world turned upside down.
