One reason of the racism in Argentina is that the most successful immigrants that we had, they come from Northern European countries.
Most of the women like to became fair hair, I never saw an authentic fair hair women wish to become brunette.
Also the german-saxon looking for a man (fair hair, blue eyes) are a clear advantage in this country, although few people will recognize it.
Northern european people brought us science, technology, hard working values. The others did a good job as well, but not so considered important,
I never saw a country without a hint of racism. Even in Italy, to be a northerner make a difference.
