All these sites have to do with British Israelism or the Identity movement. They use the historical and Biblical data to reach the conclusion that the Jews are not part of Israel and have no claim to the Covenant of Abraham.
The current archeological information shows that Europe plus offshoots are descendents of the ten lost tribes of Israel. That leaves the unlost tribes: Judah, most of Benjamin and some Levites, which descendents are here and known, and most certainly are the heirs to that covenant, since they are part of Israel.
Now, this has been pointed out to you several times. The imlications have been explained to you many times, i.e. that the Jews are covered under the Abrahamic covenant; they are just not the only ones. Yet you still insist that the information losttribe, I and others put out has something to do with these nutso theories.
Why is that? Do you have an agenda? Are trying to fool the uninformed? Have a reading comprehension?
