BETHLEHEM - Regina Mousalam is adamant that Palestinians are not leaving and will not leave the country of their birth, the land of their ancestry and the culture that is their pride. Bethlehem, Beit Jala, Beit Sahour and other Christian Palestinian towns and villages were built around their churches. The homes Palestinian Christians live in, the streets they walk and the extended families surrounding them keep Palestinians wedded to this hard, dry land.
