People in Georgia think they're better than people in Alabama. People in New York think they're better than people in New Jersey. It's normal human nature to try to find some way to make you feel better about yourself.
They do think that, they are also very racist people who think just because they are whiter than most Latin Americans, that makes them better. They have even been live shows from Argentina where they call Uruguayans "indios" which means Amerindians, which is very very funny since Uruguayans are actually whiter than Argentinians, those people live in a world of their own, but i feel bad for them, they have no culture, other than soccer/football and tango, Argentina isn't known for anything else.
You should know Mexicans are not the most intelligent Latinos.
That's just a cliche. I'm from Argentina and I don't think we're better than the rest.
They are jealous of Argentina.
I have seen many Latinos from Mexico or Dominican Republic that claim Argentina thinks they are better than other Latinos
