The Romans had theological problems with the Jews? The Nazis cited theological differences? The Soviets were Bible thumpers? Jeremy Corbyn, much maligned by the Jews, is an outspoken Christian? The current alt-right are mainly Christians and have principled, theological objections to the Jews?
Let's not kid ourselves.
I ask you again, and let us be honest with ourselves: why do you suppose that anti-Semitism is a crosscultural, ancient, widespread phenomenon, a phenomenon which is not limited to Christian or Muslim populations?
I was watching an interview between a popular atheist and two Jews, at least one of which is an Israeli citizen. The Israeli Jew made a curious remark. Israel must exist, said he, and he has nowhere else to go, for regardless of where he goes, even should he live among the aboriginals in Australia, who have no conception of the Jew, the aboriginals would come to hate the Jew, and view them as oppressors.
What are your thoughts on this?
