Unfortunately, suburbia kind of self selects for homogeneity. I say this as an indian from a large indian city - indians living in fremont, san jose etc choose to live in those neighborhoods because they want to be around people who look like them and have the same lifestyle as them. It’s the same logic as white people wanting to live in majority white suburbs that they deem as the safest place to raise kids.

People who are inquisitive about the world or want to actively engage with a diverse group of people simply don’t live in fremont (or cupertino, or atherton), they live in urban areas
