The Bay Area is a microcosm of the world, with the second largest Chinese population outside of China, the largest Filipino population outside of the Philippines, enormous Vietnamese, Mexican and East Indian populations in San Jose and the surrounding area, Central Americans in the Mission District in San Francisco, and so on. As a result most Bay Area residents accept diversity, or at least they're more tolerant than most other places. For example, they're not nearly as bad as in rural Oregon. Rural Oregonians view Californians as foreigners, and so imagine how much harder it would be for them to accept someone who's from China or India. (However, the Portland Metro area is very liberal.) We have problems here and we need improvement but we're still way ahead of most places.
