That's an interesting question. Personally, I'd say the north of Germany has more in common with Danish and Dutch people than with Bavarians (who in turn have more in common with the Austrians than with us).

It’s a super interesting example because the Swiss German in the question would also vehemently disagree that they have anything in common with the German :)

I’m actually curious if the GP expects „yes“ or „no“ as an answer, because I couldn’t even say. It’s probably „yes“, but…
