Nordic countries is a well defined collection https://en.wikipedia.org/wiki/Nordic_countries - Greenland/Nuuk is part of them given it is a region of Denmark.

I don't think the racism can be helped short term - nordics have been isolated polities that only in past decades have had large flows of migrants from different cultures. (Well, apart from Sweden attempting to conquer Europe in the 17th century but it did not end well).

If it's any consolation nordic people can be quite xenophobic even toward each other so it's not as if they would be uniquely harsh towards specific ethnicity. Every non-native will be discriminated against pretty much equally, regardless of origin or complexion. They abhor anything unfamiliar regardless of complexion. The general narrative of historical racism in these areas is quite different as compared to more cosmopolitan western countries such as UK, France or US.

Law of Jante is a pretty good framework for understanding the nordic mindset (https://en.wikipedia.org/wiki/Law_of_Jante) - the baseline response even towards in-group members that are different will be severe.

It's changing, but change will take time.
