Well, living in Chile, I've learnt that there's no racism here BUT:
-There's classism, a lot. Both from the lower classes to the upper and vice versa. There's also a lot of anger left from the various dictatorships that ruled in the eighties.
-In some countries, here included, there's also big prejudice against native cultures like the Mapuches. "They're all lazy drunkards".
These problems mostly stem from colonial times, where the Spanish didn't respect native culture and since the Europeans were seen as the "civilized, more advanced people", the aristocrats here did everything to imitate their lifestyle.
See also: mestizaje.
But now race doesn't even matter because we are all almost the same genetically (it just happens that at least in Chile, the fair-haired blue-eyed people are the richest, but hate here is about wealth and politics rather than race itself).
Is it ok to prejudicially discriminate against someone because of your opinion of their culture?
