Whites (as a whole) are the least nationalistic people in the world - especially in western-Europe.
Really? In Africa many nation states are artificial are don't reflect the actual ethno-linguistic groups that live there, hence people don't tend to be attached to their country. Where as Europe actually has a tradition of nationalistic philosophies and has possessed some of the most violently nationalist societies the world has ever seen.
Also, I find this idea of "whites" as a people a bit silly. I mean I don't think Spanish people and Georgians are that close culturally. Across Europe people speak several different languages and have very different cultures.
Since you mentioned Western Europe, I know many people in France, the UK, Ireland, Germany, e.t.c. often see second-generation African immigrants as basically French, British, Irish, e.t.c. where as a Polish guy would be Polish. I've never really seen this "white" culture or people.
