Bigotry and intolerance and hostility to people because of their "race" or religion is a horrible thing wherever it occurs, and whoever it is directed against.

It's something Jews and Arabs have in common, being the target of that kind of thing. Just as they have a whole lot more in common - shared roots (including Father Anbraham), two versions of what is really the same religion, many of the same religio/cultural rules, such as circumcision and similar dietary restructions; and of course a special relationship with the same bit of land, which most of them have never seen.

Someday this family squabble will be over, and they'll be scratching their heads in astonishment at how it could ever have got to be the way it is today.
