> I addressed that by saying there has never been a coherent German culture

Do you think that's true for German in particular or generally for countries? Like, do you think there isn't something like French or Italian culture? I always found it very weird how people think that Germany is somewhat special in that regard that we somehow ended up without having a coherent culture.

This a US centric platform here and so many words in the US come from Germany. I just learned that "Rucksack" (for large hiking backpacks) has become part of the English language in some regions. We totally need to introduce "Döner" as well. It's not random words that join other languages.
