It has been presented by the Mexican government and some media as conflict between "Protestant" and "Catholic" natives but what is in fact going on? According to La Jornada the real issue is the formation of paramilitary militia of Evangelical (fundamentalist Protestant) ideology self described as El Ejército de Dios (God's Army).
This "religious" death squad has already been involved in many violent actions, including the murder of a local politician. They are apparently in connivance with the police, both at state and federal levels, as well as to the Evangelical groups that perturb neighboring Guatemala (there as well in connivance with the army and the totalitarian and genocidal regime of Ríos Montt, who was preacher of these cults).
"Orangist" marches in Chiapas, what else?
This God's Army is not indigenous and has as program to de-indianize their adepts. Recently they marched through the city of San Cristóbal de las Casas with the music of the Imperial March of Star Wars (the music associated with Darth Vader, you get the point, right?) Their aggresive discourse is similar to that of the undemocratic Mexican government, opposed to the Zapatista bloc, against whom they act essentially.
