Also on the topic of Europeans in South America. My parents come from a neighborhood in São Paulo that is known as being the place where the Italians are. When I was really young, there were still people there who didn't speak Portuguese properly. My mom tells me of those old Italian ladies learning how to sing the Brazilian Anthem for some citizenship process.
It is very easy to find these pockets of Europeans in South American, after all it was colonized by them.
When people imagine Rio de Janeiro, they often equate it with sunshine, beautiful people, samba, and football. That is all true, but that is not all there is.
For example, about an hour away from Rio city, up the mountains is Petropolis city. This city was the summer vacation place for the royal family, so they could escape the heat. This is a popular place there:
Palácio Quitandinha
That is about two hours drive from the beaches in Rio IIRC. How European does this look? Near it, still in Rio de Janeiro state, there is another city called Penedo. That city is also nicknamed Little Finland, yes, it was a Finnish Colony in Rio. The more you look in South America, the more you find such influences.
Down south in Brazil, closer to where @Rabble
is living than from where I used to live, there is a really quaint city called Gramado, it looks like this:
Next to Gramado, is a even cuter city called Canela:
Brazil is a really large place, you can find any kind of view you want (except for snowy mountains).
As for EU citizenship, Brazilian middle-class usually has European roots and it is not uncommon for them to have EU citizenship. For example, my grandfather is Italian and my grandmother is Portuguese. I opted for the Portuguese citizenship because my grandmother was alive at the time thus making the process easier and because Portuguese and Brazilians share a lot of culture beyond just the language, it made sense for me. That doesn't make me any less Brazilian of course, and regardless of citizenship, I grew up with the same influences and culture as other people from the same area. I faced less challenges than others given my privileges, that needs to be acknowledged.
The European influence in Uruguay and Argentina is much more visible than in Brazil, but that is because Brazil is larger and slavery played a much larger role in the (tragic and criminal) development of the country. Whatever Brazil is today can't be understood without taking into account the interplay between the indigenous people, the European invaders, and the tragically enslaved.
Similarly to what I just did, you can also find places where the indigenous population fights to keep their lifestyle and culture, in some of such places they're thriving but most often they're not. There are other places where Black culture is preserved and cherished beyond what capitalism can appropriate into products. @Luandro Pàtwy has many many beautiful stories and photos with native indigenous population. That is Brazil too, and an important and often overlooked part of all our soul. For example, I know that my great grandmother was a native Brazilian that was captured with a lasso. We don't know her tribe or where she came from. My grandmother tells us of them working in farms (as indentured workers, or modern day slavery) but she can't recall where it happened. That part of my personal history is lost. I don't know to which tribe I might be related. I can't retrace it. Whatever I am, has parts of her just like it has parts of European grandparents. In this you can see Brazil, an intersection between various unbalanced forces, it is a beautiful place with beautiful people.
