I have observed the same across a bunch of linguistically Germanic countries (DE, AT, CH, NL, DK, NO, haven't been to SE, didn't observe it in IS), and I thought of it as "cultural autism." Apparently "higher context" is the politically correct way to say it. Now I know!
Danish and Norwegian are not linguistically Germanic. If anything, German has more old Norse influences. And dutch.. Well, dutch is the illegitimate child of england and germany.
>Danish and Norwegian are not linguistically Germanic
Where do you get that notion? My education (and some googling to refresh my memory) has Norwegian, Swedish and Danish classed as "North Germanic" according to comparative linguistics. That is one subset of the West Germanic languages which most of northern Europe speaks.
Denmark is a bit better, maybe because they drink more ? Dunno.
