This topic is so interesting I had to read it from the top, and got some interesting understanding of how different culture and race see others. Having said that here is my two bits in ...
my love for travel has taken us to different countries and seen different level of discrimination and in some just respect, I guess it all boils down to the animal instinct, now I can expect some bashing on it but its all about the food chain, the ones on top i guess gets respected more then those of us at lower level.
with my indian complexión and country´s situation, my travel to Dominican, Haiti, Antellis islands, Dubai Thailand, Sri Lanka and Maldives went pleasntly.
But travelling to France and Cyprus it started from the airports they would send all indians sri lankans pakistanis dominicans etc. at one corner and when they let all the others with fair skin pass then they allowed the rest of us through like we were second rated humans.
our travel to US was a nightmare and the fact that broke my heart is that they dont even care if you have small children with you. now my best friend is Brit who made permanent home in Sweden, my dearest friend is blue eyed American. so no prejudice here but im talking of airports is because these are the face of any country there are no fake civilities there just raw honesty of how they see you or expected to treat you.
my last and most recent travel here to Argentina, airport was pleasent they did not discriminate us for the color of our skin or the Passport we carried only discrimination I experienced here is when i halt a taxi on the road more then often they just wave no, some of them dont even bother to wave and one when i was about to sit in the taxi he refused and i had to find another, I may be wrong maybe they are supposed to do that if they are not available but they seemed available to me. And everytime I sat in a taxi they ask me where Im from, but I think thats a common question!
So the answer is no, not really Argentina is pretty ok compared to some other countries.
I would also like to add, to those of fair skinned people here with blue eyes, you all are beautiful, darker people and countries find you very attractive, there are people in half of the world who pay alot of money to have fairer skin and people who actually bleach their hair to look more blonde and people who leave their own home countries including Argentina to be Americans or Europeans, so what is the opposite of discrimination?
