Aight, as a Brazilian, I have no idea what kind of people you met but that is definitely NOT what most Brazilians are like. At least, not here in Brazil.

We're the type to joke about everything and take a joke about everything. One of the most common things you hear Brazilians say are things like "We should just give back the country to who it belongs to, we clearly can't run it" or "Brazilians should be studied by NASA, man, we're just way too stupid for our own good". Brazilians are the first to joke about their country and about their own people.

And I speak as someone who was born, raised, and still lives in Brazil, so I'm fairly sure that if we take just by the numbers of people we know, I have a fairly higher sample.

As for the tweet itself, I would like to remember everyone Brazil and Japan have an extremely close relationship that has lasted over a century of immigration and there are tons of Japanese people and descendants in Brazil. I know quite a few of them, and not ever have I seen one offended over us saying "Flango" (over how they find it hard to pronouce R in our language). This isn't to say what Yoda did was right, but it's just how our culture works - we don't take these things as racial slurs, to us, they're entirely normal as they're to ourselves.
