that website let's not mention the name.. is just one of yusuf al khattab's early creations. They are not relevant.. Jews don't have a problem of jews becoming muslims. It's one in a million. Or 2 in a million!
and the few active on that website didn't have a jewish mother anyway, apart from al khattab. So they described themselves as "ethnically jewish".
They are trying to recreate the success of jews4jesus, and they're not having the same success.
