Interesting Jewish perspective.

EUOBSERVER / JERUSALEM - One of the luminaries of the international Jewish community, Rabbi David Rosen, has warned that Europe risks being "overrun" by Islam unless it rediscovers its Christian roots.
Speaking to journalists at a meeting in Jerusalem on Friday (26 November), Rabbi Rosen, the director of inter-religious affairs at the Washington-based American Jewish Congress, said that a predominantly secular and liberal Western European society is under threat from the rapid growth of Islamic communities which do not want to integrate with their neighbours.

"I am against building walls. My humanity is my most important component. But Western society very clearly doesn't have a strong identity. I would like Christians in Europe to become more Christian ... those who do not have a strong identity are easily overrun by those who do," the rabbi warned.
