"But many Jews were deeply offended by that decision, offended by any hint that Jews could be considered a race."
Yeah the reason for that is that it would throw up the very awkward issue that Jews are not the only Semites, eg, the modern Palestinians, both Christian and Muslim, are also Semites. The are no racial differences between Palestinians Jews and Palestinian Christians and Muslims - they share the same DNA.
So to get round the little problem the Zionists had when they decided to steal the land from the Palestinians, they chose to call themselves "a people" ..... preferably a "Chosen People", which very conveniently excludes all non-Israeli Palestinians. That's chosen by God btw.
Obviously many Jews have non-semtic DNA, specially North European DNA. But I notice TurnerGuy that you chose to call Elfin "anti-semitic", why would you do that - if you reject the claim that Jews are a race?
Defining yourself as a Jew does not have anything to do with religion, in fact half of the Jews in Israel are "secular" Jews........clearly religion, contrary to your claim, is not the deciding factor.
Jews are a race, but they share their race with other people. In the same way that Kurds can be racially identified, despite the fact that do not constitute a separate race.
