on WSJ years ago of a tribe in Africa that was Jewish and had DNA proof of links to the tribe of Levi (the priestly 'tribe' which was not actually part of the original 12)--
but when most of them went to Israel they were not welcomed with open arms, being, ahem, dark of skin.
FBI Exposer hasn't been on here for a while, but he adamantly insists that the European Jews are as Jewish as anyone anywhere--and expresses his opinion forcefully, something about a particular chromosome; he says the same thing over and over again, and I think he also questions the intelligence of anyone who tries to discuss the other options with him--
I think it's quite amusing that it is sometimes hard for people to tell Palestinians/other Middle Easterners and Jewish Israelis apart--
some of the European Jews are quite light, true--
but many of them are not, and many people can 'pass' for the other--
it's hard to be awake; it's easier to dream--
