The fourfold models used to describe individual attitudes of immigrants parallel models used to describe group expectations of the larger society and how groups should acculturate.  In a melting pot society, in which a harmonious and homogenous culture is promoted, assimilation is the endorsed acculturation strategy. In segregationist society, in which humans are separated into racial groups in daily life, a separation acculturation strategy is endorsed. In a multiculturalist society, in which multiple cultures are accepted and appreciated, individuals are encouraged to adopt an integrationist approach to acculturation. In societies where cultural exclusion is promoted, individuals often adopt marginalization strategies of acculturation.
But of all the places that I have visited, the only place that I’ve been to enough to actually make real friends is Jamesport, MO. If one judges friendliness by warmth and outgoing-ness towards an individual you don’t know, then Jamesport Amish are probably about average-to-slightly-above-average. However, if you measure friendliness by a perspective that is more than just a smile and a friendly hello, but is open to accepting others as genuine friends — well, Jamesport has to be one of the best places I’ve been to. But then again, I might find other places equally friendly in that way if I could invest the same time and personal involvement.
