It is fairly common for the internet to ignore the kind of alienation felt by immigrants in an (intentional or accidental) ethno-state.
We hear more about racism in the US, UK and similarly 'diverse' countries because there are more interactions that enable that. We hear of religious tensions in India and France because both countries have enough diversity for discussion/conflict to be a possibility. In ethnically homogeneous countries, you get drowned out before you even realize it. The part that often gets ignored, is that it has very little to do with the human development of said country. Scandinavia and East Asia have the same or even greater propensity for racism as the common offenders. They just don't have enough interactions for it to get surfaced.
Scandinavia, or at least Sweden and Norway are pretty diverse places now. Sweden's population is 20% foreign born and Norway's 17%, compared to 14% for both the US and UK. (Finland and Denmark are much lower at 7% and 8%.)
