1. Ancient Greco-Roman racial anti-Semitism doesn't make much sense when one knows that Jews are genetically closer to Cypriots, Greeks and southern Italians than to anybody else, even in the Middle East. Anyway the Greeks and Romans regarded all foreigners as barbarians. The Romans did not hesitate to commit genocide even on Celtic tribes that were ethnically related to them. Actually in ancient times genocides were common practically everywhere, and is even
recommended by the Old Testament.
3. Traditional Muslim anti-Semitism is an oxymoron since Arabs are also Semitic people. The Koran does grant special protected status to the other people of the Book, namely the Jews and the Christians. Where Islam is intransigent is against pagans and Atheists. So Islam cannot be called anti-Jewish, even less anti-Semitic (obviously), but is clearly anti-pagan and anti-Atheist.
For the rest, anti-Semitism in Europe was always both religious and racial for the good reason that the term Jew conveys both religious and racial meanings. The two are so indissociable historically that it has become a real problem for modern Jews and for the Israeli state to define
who is a Jew and who is not. The problem is that 40% of American Jews are Atheists but still consider themselves Jewish, as an ethnic definition. In Israel, Jews come from so many different horizons and are so genetically different (e.g. Ethiopian Jew vs Russian Jew) that only religion unites them. If even today the Jews themselves
can't agree on what it means to be Jewish, how would you expect non-Jews in past centuries to know ? Therefore it is both mistaken and pedantic of this Jerome Chanes to try distinguish religious from racial anti-Semitism in European history.
The political, social and economic anti-Semitism is essentially the same as racial and religious anti-Semitism too. Socially the Jews were always excluded (or excluded themselves) from the mainstream European society. The reason was purely religious though, and the consequence was that they remained ethnically distinct from other Europeans. You can't separate the social from the religious and the ethnic. It's all one and same thing. Economically the Jews were richer because they specialised in jobs such as money lending that was traditionally prohibited to Christians. So once again they different economic status has religious roots. The political expression of anti-Semitism rose because of resentment towards this ground of people who were ethnically and religiously distinct
and accumulated considerable wealth. No matter whether it was in the 18th, 19th or 20th century, political anti-Semitism was always caused by these three factors, who all have their roots, ultimately, in religion. So anti-Semitism in Europe was always a religious conflict, even in Nazism. You just can't separate racial Jewishness from religious Jewishness in anti-Semitism. If you can then please advise the Israeli state on who they should accept as new citizens.
