Culture of hospitality exists is many other places that has nothing to do with Bible. Example Afghanistan

Also due to ancient tradition. My general experience is traditional cultures are nicer. Hospitality is usually a sacred value, e.g. Bible's story of Abraham unwittingly being a host to God.

Your point of course stands, but this example may not be ideal. It is a country where the predominant religion follows ideas very closely related to those in the Bible.

I think this is absolutely true, but you'd think the Quakers would have left some wholesomeness in the Northeast as well, right? I would hope that we don't need to depend on religion, hundreds of years later, to instill good values in our children.
