Pretty certain he’s saying that certain groups of Latinos look “down” on other groups of Latinos. It’s similar to Americans of Northern European descent putting up “No Irish” signs or discriminating against Italians, Slavs, Poles, etc.This is puzzling.
Without a doubt, many Spanish Latinos look down on Indigenous Latinos AND black Latinos. The “whiter” or more European-looking, the better.
Many (most?) Cuban-Americans pretty much look down on all other Latinos in the US. The Cubans who fled when Castro overthrew the Batista dictatorship were largely Hispanic Cubans. They certainly were not Afro-Cubans and few were of indigenous heritage.
In many cases, the elite governing classes in Latin America were mostly of European heritage. They dominated and/or enslaved the indigenous people (similar to the United States and Canada). Europeans conquering indigenous people were not exactly kind.
It’s likely that Latinos in the USA who have fled Communism regard themselves as higher up the food chain than indigenous people looking for a better life.
Basically, not all Latinos are the same.
