uhmm... I'm argentine. I live in the zona sur del gran Buenos Aires and I know pretty much most of it (at least from Avellaneda to Florencio Varela and Solano). I travel constantly to capital (luckily not very often because I hate the city) and I have been to pretty much all the barrios. I know some parts of zona oeste, zona norte and La Plata. I haven't travelled that much to the interior but I have been to Rosario, Cordoba, Mendoza and Entre Rios (all the "whiter" provinces). I have two eyes and I can notice that we are mostly mestizos, not white. In Palermo and Recoleta, you are right the population is mostly white. What about Jujuy, Salta, La Rioja, Catamarca, San Juan, Santiago del Estero, Formosa, etc. I have never been there but when I see some footage of those places on TV mestizos are everywhere. Maybe someone who has actually been there can enlighten us.
And why am I a racist? Because I say we are mostly mestizos? That doesn't make much sense. If I were a racist I would close my eyes and think and dream we are mostly white Europeans (like many white Argentine tend to think).
OK.
