You should probably consider if your own fears are biased. There seems to be a tendency to assume that racism is more prevalent than reality in many areas of the country, fueled by the internet and the media. I live in a suburban, Midwestern area that is absolutely more diverse and welcoming than those on the coasts seem to think. Of the 6 households nearest to mine, 3 are white. The other 3 are Indian (first generation immigrant), Chinese (second generation), and Eastern European (first generation). I work at a smaller startup now, but at my previous job, my team was white-minority. Most people on my team were East or South Asian, including my boss.

I have no doubt there are racists here, especially in the rural areas. But I also have no doubt that the same holds true for places like California and Washington. You may be keeping yourself from experiencing areas of the country that you may love and would love you back.
