I'd say the Children of Israel - the descendants of the 12 tribes of Israel, the sons of Jacob - are a genealogical group.
IIRC, DNA studies show that most Palestinian Arabs also share the genes with Israelites.
My words, as you've quoted them, are quite clear - I've said that only the minority of the descendants of the 12 tribes are today 'of the Jewish faith'. Secular Jews are included in this - they are just non-practicing Jews - I'm specifically contrasting this with the numbers who are converts to other religions.
As I stated in the other thread - I agree with Professor Porath and dismiss both the Arab myths and Zionist myths. I'm sure I said that a few times at least.
