Greece has Jewish and Muslim citizens, but is a staunchly Christian country; it celebrates Christian holidays, the cross is a national symbol, and institutional preference is given to Christianity. America proudly declares, “In God we trust,” not fearing to offend polytheists. France refused official status to the language of its large and compactly settled Breton minority.

Preference should be distinguished from discrimination. State-level religious advances are a matter of preference. There are many preferences around. Government tenders prefer the lowest price to the highest quality; such a criterion arbitrarily benefits some producers at the expense of others. State-owned European cathedrals host Christian services, never Jewish ones. Governments build roads even though the same funds could benefit poor or ill persons. Public entities, like any others, have to make choices, and choosing means arbitrarily preferring one thing to another. Judaism in Israel, and Christianity in Greece, are the preferred religions.

Discrimination is not merely the absence of preference, but purposeful harm done to a narrowly defined group. A ban on Islam in Israel would be discrimination (though not an unreasonable discrimination, given the Torah’s dictates). Similarly, a ban on Palestinian symbols and songs would discriminate against Arabs, but the absence of Palestinian symbols on the Israeli flag and the absence of any mention of Arabs in the Israeli national anthem are consequences of a preference for Jews.

If the Arabs don’t like that, they are free to leave and enjoy every detail of Muslim symbolism, including a ban on Jews, in Saudi Arabia or Jordan.
