Last I checked, Spain was in Europe.
Saying Miami is more Latin American than Buenos Aires is stereotypical and prejudice because this statement suggests there is something intrinsically Latin American about Latin America. Latin America is a huge space (a population of 580,086,590 which the parent seeks to generalize), there are various cultures and subcultures, various languages and dialects. Whatever J. Lo has brainwashed people into thinking is "Latin American" is not all-encompassing and should not be representative of it.
Thus, Buenos Aires is just as very Latin American as La Paz or San Juan or Rio de Janeiro or Havana.
The fact that more Italians immigrated to Argentina does not make them more "European", since Spain, the country that colonized most of Latin America is European. Since its colonization, Latin America adopted a lot of traditions from Spain and the rest of Europe, thanks to many Latin American governments asking for more European immigrants to "fill the void" and work the land. However, not all countries adopted the same traditions to the same degree and some preferred other European traditions (that could also be shared with Spain, Portugal and the rest of Western Europe).
Thus, the statement "Buenos Aires is not particularly representative of Latin America, it's more like a hybrid between LatAm and Europe" is wrong because most of Latin America includes Europe in its transculturation, acculturation, syncretism, miscegenation and hybridity.
But all of those things are true only to a tiny extent in Buenos Aires, and a more noticeable but still small extent in the rest of Argentina. This is what genocide looks like.
So I wasn't saying that Argentina is more European than Bolivia, Puerto Rico, Brazil, Cuba, or Miami because it's less Spanish. I was saying that Argentina is more European than Bolivia, Puerto Rico, Brazil, or Cuba because it's less American, because none of the things I said in the previous paragraph are true here, and they're still true in those places. The most distinctively American thing about Buenos Aires is that everybody drinks yerba mate.
By the way, Diego grew up here in Buenos Aires, where I also live. So however much you may disagree with our conceptions of what "Latin America" means, you can't blame poor J. Lo for them.
"Thus, the statement "Buenos Aires is not particularly representative of Latin America, it's more like a hybrid between LatAm and Europe" is wrong because most of Latin America includes Europe in its transculturation, acculturation, syncretism, miscegenation and hybridity."
If you travel to different Latin American countries you'll realize the difference beyond any forced formalization/logic of a statement.
