Among the educated and financially comfortable people I know, it seems to just be tribal. Boca or River.
Oh, yeah...the tribal thing,,,
I forgot about that. That's what happens when you live 32 years abroad.
"What I think is what is true", "the worst thing for an Argentinean is another Argentinean", "look at France and look at us", I should stop...
The "anticapitalist"/peroncho thing is the paternalistic "caudillo" phenomenon that never went away in Argentine history. Those are the ones that never bought into the European (or US) model because they never felt part of the continuum of out-of-their-grasp Age of Reason or Humanistic concepts.
After all, the continent was invaded and colonized by Europeans and, through the good graces of the Jesuits during the Spanish conquista, the vast majority of the overall population in Latin America are descendants of native people and their creole mix. They survived and are the overwhelming majority in that huge continent. I live in New York City and the only native people I see here are from Mexico and other Central American countries (lots of Mayan people).
I like to talk to them and ask them how they are faring in this alternative reality. It's sad to see them alone and many of them drunk during the weekends where they don't have a place to go where they could fit comfortably or they could afford. They walk like ghosts in the night.
Latin America has had so far only one democratically elected president of native origin after six centuries (!) of occupation. Evo Morales, whatever our opinion of him, is an anomaly that confirms the fact that that overwhelming majority of native people are never politically represented in those regions.
