in s/introductions a guy said that the talmud is basically a giant jew cope for the murder of their own messiah

There's definitely some of that I think

Also you have "hasmonean wars" it's when jews took up arms to mass murder heleznized jews and non jews on their turf, over "purity concerns"

So, this doesn't point at the source of the phenomenon, but it shows that it's far from being new

They run on a "us" vs the world set of ideas, and since 4hey don't have the numbers, they have to rely on pitting their enemies one against another I think

I don't know either.
