That's utter claptrap and a long banned poster used to post threads about the lost tribes all the time.Jim doesn't like this kind of tinfoil posted to Fr,which is WHY he was banned.
I agree with you No Pardons on that Lost Tribe website's credibility.
BTW, it's not nice to refer to another poster without pinging them.
The poster you mentioned was banned because he was too confrontational, consistantly forced his topic on threads having nothing to do with that topic, tended to be rude and first to anger in his debate, and picked fights whenever possible. Much the same reason that poster, Whiskey Papa, that haunted the southern/civil war threads was banned.
I debated on the side of the notion that the remnants of the 10 tribes of Israel make up a large part of the world today, and I'm not banned.
BTW, I agree with you about the Rapture. All I have read about it's Biblical support can also be interpreted to mean that God will cleanse the Earth of deadwood so He could bring the Millennium age.
