I take your point on the "race"coming into the thread.
You then posted
"There were, of course, no jews until Abraham led a goup of followers from Basra (Iran/Persia) through to the western side of the middle east collecting more followers (Arabs) as they went. Black Jews in West Africa are not the same same race as the 'originals' and nor was Sammy Davis Jnr. and nor are many others that subsequently took up the religion. Those that want to claim links to the 'originals' are almost certainly Arabs or Persian - i.e. semites."
My source is the bible which I believe is a better document than whatever you have sourced. The same bible has been in circulation for 4,000 years. Can't say the same for your source.
Your source refers to Abraham. The bible narrates that he was the first Jew and that he then circumsiced his son, then his male household members etc etc. There was only he and his wife at the beginning. I'll stick with the Old Testament version, you can keep to yours including Sammy Davis Jnr who was as Jewish as Gaweb is normal.
