Are you objective?

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.

I'd definitely not be objective at all, but I'd try (difficult to know if one actually succeeds) to be objective when it comes to anything that concerns other people's lifestyles or difficulties, which mainly concerns not judging them or thinking I'm aware of all issues those people might face, but also not be pitying which is just a silly narrative.In addition to that I try to be objective with major issues like global warming, e.t.c. and beyond that apply general fact checking skills to topics I don't know anything about. To be honest I find the most efficient thing to do is read Wikipedia, in the areas I know about it's quite good, so I start off with it on things I don't and check around on good blogs (blogs of experts) to see if it's reasonable and develop my understanding.Of course I'd have the bias that I only do this for things I'm interested in, so I'd try to have no opinion on things I haven't read up on. "Try" being the operative word as it is surprising how many opinions you absorb by osmosis based on what people of one's background typically/should believe.
