There is more to Jewish history than Auschwitz.
Zionism is the most stupendous fallacy in Jewish history
In Jewish history there are no coincidences.
It's very clear from Biblical history and Jewish history that Jewish monotheism wasn't developed in an instant, that it became gradually the accepted norm. But undoubtedly, Jewish ancestors were polytheists.
I think Jewish history did away with a priesthood when the Temple was destroyed, and it became, supposedly, a religion of scholars. A rabbi is just a scholar.
