Shame that people are down voting you, there's an uncomfortable truth to it I don't think people want to face.

Culture is defined by people not borders- simply crossing an arbitrary line doesn't change someone's beliefs and values.

The immigration boom especially on the West coast has vastly diluted assimilation into American culture- coming from an immigrant, who married into another family of immigrants- too many people move here and stick to their own cultural enclave, building a version of their home country in miniature instead of trying to integrate.
