Which gives me pause. German speaking countries have a wide range of dialects, even regional. I am able to tell a guy from Vienna from someone from Tyrol. Upper Bavaria from Lower Bavaria, Berlin from Hamburg. There are older people who can tell from Bavarian county and which mountain valley you are. The latter becoming more difficult, so, with people moving around. Just imagining to use these differences to discriminate people gives me the chills, because it would so damn easy to do. And also, at least superficially, maybe even legal.
