I honestly find that surprising. Germany is the place in Europe where there is the most white guilt. I stayed there for a few months and experienced zero problems.
I have a lot of (brown) Asian family relatives who've spent decades in Germany, they tell me America is basically a heaven in comparison. Canada is pretty much the only country that comes close to America (according to them -- and my experiences ring true here as well), in not being racist to non-white individuals.
That doesn't prevent a latent racism in big parts of the population.
Simply growing up with almost no non-whites makes everyone who looks different stand out a lot, and the step from standing out to shunned out is quite small, I'm afraid.
