I find it hard to understand how many people, both Jews
and non-Jews, claim that there is such thing as a Jewish "race". Yes, I know that Judaism
developed amongst the Semitic
peoples of the near- and middle-East, but that was many thousands of years ago.
If the Jews are a unique race of people, how can one explain the Beta Israel (Ethiopian Jews) who are ethnically as Ethiopian as Haile Selassie but are religiously recognised as a sect of Judaism, and are perhaps even the descendants of the Lost Israeli Tribe of Dan.
It's also possible to convert to Judaism - but in doing so one obviously does not change one's ethnic background. And with far greater mingling of Diaspora Jews with their host communities these days, including a considerable degree of intermarriage, I'd be prepared to argue that the traditional Semitic origin of most Jews is rapidly becoming diluted and of little importance.
