They carry the curse of Cain. The dec3nd2nts of Cain were the first city builders. Jews are always urbanites.
They are descended from the first murderer. They are cursed by God.
I know that bringing up the Bible gets you labeled as an idiot, but the analogies are there for anyone to see. The underlying Truths don't change with the changing of the Ages. Even with all of the new technology, the world is still an illusion. And human nature does not change.
And when it comes down to the True things in the world, there is nothing new under the Sun.
The curses ones have been with us since the beginning. And they will be with us until the end. And the cycles will continue.
