I assume by your username that you're from Brazil? If that's the case, your statement makes perfect sense. Based on my limited experience, there're some really unfortunate attitudes towards Brazilians in Portugal.
As an American, the locals were super-nice, and compared to the rest of Europe the cost of living is very low.
