Even worse, there's the made-up word or label of the "Latino" or "Hispanic."

Nonsense, those people aren't European.
Most Mexican fighters are clearly indigenous peoples of this continent with some European ancestry thrown in. Erik Morales is very clearly a First Nations person. The USA calls them Native Americans or North American Indians. Anyway, that's what Morales is even if the USA govt descended from European immigrants insist on calling indigenous peoples on their own ancestral continent "illegal aliens."

"Latino" and "Hispanic" are cultural heritages, and ways to deceive people of who they really are.
