The issue is not so much one of blood, but belief.

Ideals are not absolutes.

Truth, beauty, platonic forms are ideals. The core codes, creeds, heroes, narratives at the center of every culture are ideals.

The universal, on the other hand, is the elemental. A spiritual absolute would be the essence of sentience, from which life rises, not an ideal of wisdom and judgement, from which it fell.

To the Ancients, gods were metaphors. Monotheism equated with monoculture. One people, one rule, one god.

To Judaism, the ideal is the tribe. To Catholicism, it is authority. To Islam, it is law. To Protestantism, it is community.

Tribalism is elemental to humanity. For millions of years we evolved as members of such groups. It has only been in the last 3000 that we have grown beyond that, to nations of millions and now billions of people.

We have had to evolve more extensive networks in what is an evolutionarily short span of time.

Basically Israel, as an idea, is missing that 2000 years of diplomatic evolution. Too many shamans and no chieftains has left the culture with an isolated sense of the larger world. The Zionists are re-litigating the conflict the Maccabees had with the Romans.

My sense is that most Jews, at least where I live, are not real happy with the crazies dragging the culture through the mud. Much of the backing comes from the fundamentalist Christians, who seem to think Jesus will save their sorry asses, if they fight the infidels.

These people have as much insight as the crazies on the other side, looking for their 72 virgins.

Which is to say, logic and science are not going to win this argument.

About the best that can be hoped for, is the debt backing all this nonsense blows up, before they blow up the world.
