This is a very good example of someone trying to talk about something which have absolutely no idea. Also I received your comment as a rude insinuation that Brasil may be a former nazi alley. Beside, you were prejudicious because putting 'germans' and 'war' in the same phrase gave the impression that you are tagging ALL the germans with the nazist label. And to make things still worse you accused my country of being a place that embrace criminals. You should be more careful when posting unless when you are intentionally trying to insult others. I absolutelly hated your comment.
Anway, there is NOT germans here. Well maybe there is, but this is not their neighbourhood. The Sao Paulo state is well known for receive foreigners from all over the world since the beggining of the XX century being mostly italians and japanese. Here in town, the strongest foreigner colonization was from japaneses, but even their presence here today is not too perceptible. Mostly of the population is fulfilled by brazilians for the whole country, specially the ones coming from big towns and looking for a smooth life.
The germans are concentrated in the south of Brasil, specially in the state 'Rio Grande do Sul'.
