Orwell, right again

Is it inevitable that anything will decay into its' opposite? Contemplating the violent racism of Israel, it's hard not to conclude so. To quote one of its founding fathers, Uri Avnery:

THE ARCHBISHOP of New York announces that any Catholic who rents out an apartment to a Jew commits a mortal sin and runs the risk of excommunication.

A protestant priest in Berlin decrees that a Christian who employs a Jew will be banished from his parish.
Impossible? Indeed. Except in Israel – in reverse, of course.
The rabbi of Safed, a government employee, has decreed that it is strictly forbidden to let apartments to Arabs – including the Arab students at the local medical school. Twenty other town rabbis – whose salaries are paid by the taxpayers, mostly secular, including Arab citizens - have publicly supported this edict.
