Mexico's founders, like other nations' founders, include explorers. Unfortunately, many of these courageous men (few women were either permitted to do things on their own or were given credit for their discoveries) weren't Mexican or pure Indian. Mexico's heritage includes explorers and conquerors who were native Indians, Spaniards and others of inconclusive ancestry.
It is known that of the Indians who first populated the United States and then Mexico, some were involved in a natural earth-oriented (agrarian) existence while others were warmongers (pillagers). Nevertheless, these pillagers continued an Indian way of life, alien to the non-hedonistic cultures of the Anglos that arrived with the European boats that brought Spaniards and other Catholic heritage cultures and races.
These explorers included caravans of French, Spanish and Austrian "warlords." Spain's role in Mexico includes negative exploitation of Mexican natives. Spaniards so penetrated Mexico's various regions that Mexico's "native tongue" became an amalgamation of various Indian languages; Spanish, some English and tailings from other visitors-turned-residents.
Mexico is American Geography
Your author has met many people proudly calling themselves Mexicans who are not Spanish, as commonly thought, but are instead, proud Indians of Mayan or other tribal heritage who originated in Asia, tens of thousands of years ago (similar to the Indians who settled in the United States), came across Alaska and, after walking down through pre-Anglo United States, settled within Mexico before other explorers arrived by boat.
Mexicans are Americans
America is a geographical description; All citizens from Alaska to the southern tip of Peru are Americans! Some are South, some Central (Mexico is part of America) and the rest are North Americas (Canadians and citizens of the United States!) It's interesting that most Anglos from the United States fail to realize that Mexicans are more American than anyone who arrived from Europe with Columbus!
