I have never heard of "king jimmy" and no Babylonians foisted anything on the Jews of 2500 years ago, except perhaps for the Aramaic language.
Sadducees are extinct, and the Karaite sect emerged about 1500 years ago.
In any case, it's only the Pharisees and the talmudic sages who have used the title of "Rabbi" and since you reject their authority, you have no claim to it, or even any reason to use it.
My post #73 was finished and posted about an hour after I first started it, so I am just now catching up on some of the posts. Maybe I should have asked one of you guys my question.
