I have worked in California, Virginia, and Germany, and I've seen racist contexts in all these locations. East vs West Germany: Yes, perhaps the east is somewhat more opposed to outsiders, but only in the country side - cities like Dresden, Berlin, Leipzig are similarly diverse as are West German cities. And if you go to a rural area in Bavaria, you'll find (former) Pegida as well. It is just not as simple as the generalizations made by you and others.
