I certainly realize and also know that there a quite few different factors in culture which also influence people. It is not common cliches and prejudices.
For Germans Goethe is very important whereas in Scandinavia he is just another good author in the world litterature.
Christmas traditions vary within Scandinavia and are different to the German traditions.
I could list many things and non have to do with prejudices, but in my eyes make things more interesting.
Denmark has a cultural kanon where the things of importance are listed.
Architekture, Paintings, Design, Film, Litterature, Musik, Popular musik, Theatre and children´s cultural kanon.
These things have influenced the Danes over generations and problaby the majority of non Danes have not even heard about certain things listed. Just as I do not know all the things which is culture in other countries.
Forget IKEA, but the way a house is furnished differes in different countries, that is also a part of daily culture.
