One of the most bizarre aspects of this "re-racializing" of anti-Semitism is the role played by the Khazar myth.
It would be hard to exaggerate how widespread the misuse of the Khazar myth is among those seeking to delegitimize Israel and Jews today. A recent investigation showed nearly 30,000 websites using the Khazar "theory" as a bludgeon against Israel and Zionism.
Arab and Islamofascist propagandists have long bandied about the Ashkenazim as Khazars theory and Iran's genocidal leaders adore it. Al-Jazeera has been using the Khazar story to urge a worldwide Christian religious war against the Khazar pseudo-Jewish imperialists.
As The Encyclopedia of Judaism (1989) emphatically states, "The notion that Ashkenazi Jewry is descended from the Khazars has absolutely no basis in fact."
So what are we to make of the Khazar myth concerning Ashkenazi Jews and their supposed lack of legitimate claims to Israel due to their Khazar origins? The greatest irony is that even if the entire Khazar theory of Ashkenazi Jews were correct - and virtually none of it is correct - it would be entirely irrelevant. Judaism has never defined Jews on racial grounds. Anyone from any race is welcome as a convert to Judaism as long as he or she is sincere.
The biblical Israelites themselves were already a racial hodgepodge. They absorbed the "mixed multitude" that left Egypt together with them at the time of the Exodus. There are biblical references to Jews of different racial features, including the black-skinned Shulamit mentioned in the Song of Songs.
Jews always defined themselves in religious, ethnic-national and at times linguistic terms, but never along racial lines. If all Ashkenazi Jews were indeed converted Khazars, as the racial anti-Zionists claim, they would be no less legitimately Jews - and, as such, would have the same legitimate claims to the Jewish homeland as any other group of Jews. (Given the traditional Jewish deference to righteous converts, maybe more so.)
The actual details of the Khazar theory concerning European Jewry are simply pseudo-history and crackpot poppycock.
Jews already lived in Europe a thousand years before the Khazar kingdom was formed. There are no genetic markers or indicators at all showing that Ashkenazi Jews are descended from Turkic tribes. In fact, there exists considerable genetic evidence showing that European Jews are closer to Levantine and Syrian Arabs than to Central Asians.
After the Mongol invasion most Khazars probably assimilated into the Jewish communities of Iran and Iraq, which of course eventually emerged as important Sephardic centers, formed mainly of Jews with Semitic racial characteristics, descended from migrants and exiled Jews from the Land of Israel. In any case, there are more "Semitic" Sephardic Jews in Israel today than there are European Ashkenazi Jews. And if the Khazars looked Turkic, how on earth could they give Ashkenazi Jews a European complexion?
There are other problems. If all Ashkenazi Jews are descended from converted Khazars, why are there Cohens and Levis among them? One inherits the status of a Cohen (priest) or Levite from one's father. Descendants of converts through the male line can never be a Cohen or a Levite.
And why are there no Khazar surnames among Ashkenazim, or Khazar names for towns in Europe where Jews lived? And why did most Ashkenazi communities speak variations of Yiddish rather than Turkic?
As mentioned, the popularity of the Khazar myth among anti-Semites represents a return of modern anti-Jewish bigotry to the racialism of the 1930's and earlier.
Nearly every anti-Semitic and neo-Nazi website denounces Zionists and Israelis as "Khazars." Web chat lists in which Jews defending Israel are dismissed as "Khazar usurpers" are too numerous to count.
The racialism once again in vogue holds that Jews would only have legitimate claims to the right of self-determination in their homeland if they were appropriately Semitic from a racial point of view. Palestine is part of the Semitic racial lebensraum and those who do not possess the correct pure racial markings have no business being there. Racial purity is suddenly the new basis for national rights.
