You have a problem as the Children of Israel in the old testament were clearly not white to begin with and many were obviously of African descent. Moses married and Ethiopian woman, so the descendants of Moses are not white.
Your analogy not only doesn't work, it is clearly offensive as is your last sentence.
The fact is that God showed favor to the Jewish nation and to the genetic descendants of Abraham, Issac and Jacob. If you can't deal with that fact, then that is your problem. I see no problem with God having a "chosen" people and that God chose them for his purposes and for his own reasons.
The FACT that God chose the descendants of Israel to give blessings to has nothing to do with The White Race.
You lose.
BTW, IBTZ
Why is it that when it comes to practical application, the purist calvinists have more trouble with "Jacob have I loved and Esau have I hated" than do us double-predestinarian, quarter-pelagian, calvinists in the tradition of Arminius?
Actually, British-Israelites will claim that the original inhabitants of Egypt and upper Ethiopia were... Whites.
Now you're just debating archaeology and Genesis-interpretation.
However, in even addressing the question, you've already admitted that the British-Israelite/Christian-Identity folks are Racially-dividing the Body of Christ along Ethnic lines. As Winston Churchill reputedly said to the Lady of Ill Repute -- we've already established where you're coming from, now we're just arguing about Price (or in this case, "Which Ethnicity", which Racial Division... which Sundering of the Body of Christ do you prefer?).
