I don't think the left is as coordinated as wrestling promoters were - it's just that they share such similar impulses. And they definitely do work together in a number of ways.
And, again, your resentment of Catholicism creates the only false note in the piece: Mexican nationalists do not argue that: "their Spanish-speaking Roman Catholic ancestors allegedly lived happily in until the "rednecks" sent Christopher Columbus over here to louse things up."
Mexican nationalists have for decades portrayed the Catholic Church as one of several key instruments of colonialist oppression. Mexican nationalist demonstrations, protests and marches never adopt a Catholic identity or even a Spanish identity - they look to the Aztec Empire and the anticlerical revolutionary nationalists like Villa and Zapata for their inspiration.
I understand your brief against the Catholic Church, but the Catholic Church's historical role in Mexico is, and always has been, associated with: (1) Spanish colonial sovereignty and European "cultural imperialism", (2) opposition to revolutionary independence movements in Mexico, (3) opposition to most social legislation in Mexico (compulsory public education, compulsory civil marriage, conscription, nationalization of land), (4) resistance to the second Mexican Revolution and the Zapatista movement.
To the advocates of "Aztlan", the Catholic Church is only just below the United States in their demonology. Their precious native languages and cultures were destroyed by the clergy who abolished their ancestral, environmentally-conscious religion that made them one with the land, and the Church imposed the tongue of the Spanish oppressor on their proud warrior ancestors turning them into meek slaves who almost forgot their heritage.
Thank you for your kind comments. Please allow me to correct this misinterpretation of yours and perhaps put your mind at ease.
The remark about "indigenous Spanish-speaking Roman Catholics" was actually tongue-in-cheek. However the Spanish are regarded in Latin America, in the USA Spanish language and culture are treated as if they were an indigenous "third world" language/culture. Militant Hispanic leftists proudly refer to themselves as "Hispanic" and "Latino," and Hispanic Catholicism is (like Black Protestantism) an aspect of revolutionary "otherness." Please recall that the late Cesar Chavez during his heyday staged "stations of the cross" and masses and was loudly supported by the same leftists who were at that very same time bashing Catholicism and the Vatican.
Please understand the statement in the spirit it was made (you don't honestly think I believe Christopher Columbus was sent over here by "the rednecks," do you?).
In Canada the French Quebecers are treated as if they were "indigenous" third worlders.
Again, thanks for your comments.
