Absolutely not true, it means you might e.g. be living in Berlin, or in Germany or Netherlands in general. Not everywhere people are nice and in some places they place a particular pride in being assholes.
It's like, no, some places really are just filled with assholes.
Maybe in America it's still true, but there I also feel like it's changing for the worse as well.
Not many friendly people walking around this planet anymore it seems.
