All kids think some other family is perfect. - Sheri S. Tepper

As everybody's god, what will you do?" The doctor demanded.
"You mean immediately?" asked the small god. "I will raise up prophets to make conflicting pronouncements that will inevitably be garbled in transcription, resulting in mutually exclusive definitions of orthodoxy from which the open-minded will flee in dismay...Also, I will be capricious. I'll reward and punish arbitrarily. I'll peek through bedroom windows and admonish what I see there, sometimes one thing, sometimes the opposite. I will have purposes men know nothing of, and when men begin to catch on to them, I will change them. This will convince some of your people that I am unreliable...Occasionally, I will do a conspicuous miracle to save one dying child while a thousand children starve elsewhere. This will convince sensible people I am perverse, and they will curse my name. Be sure to recruit those who do, they'll be invaluable. Only by repudiating both devils and small gods will they ever know the Real One.
I will be a sham, but not a snob. I will let every man, woman, or child, no matter how greedy or wicked, claim to have a personal relationship with me. In other words, I will be as arbitrary, inconsistent, ignorant, pushy, and common as humans are, and what more have they ever wanted in a god?"
"The truth!" cried the doctor and Arnole, simultaneously...
"Oh, tush, they never wanted anything of the kind. Creation has the truth written all over it—the age of the universe, the history of the world—but nine-tenths of mankind either don't know it or think it's a sham, because it isn't what their book or their prophet says, and it isn't cozy or manipulable enough."
"My people wanted truth," said Nell, stiffly. "My friends."
"They were a minority. Not many years before the Happening, one of your country's largest religious bodies officially declared that their book was holier than their God, thus simultaneously and corporately breaking several commandments of their own religion, particularly the first one. Of course they liked the book better! It was full of magic and contradictions that they could quote to reinforce their bigoted and hateful opinions, as I well know, for I chose many parts of it from among the scrolls and epistles that were lying around in caves here and there. They're correct that a god picked out the material; they just have the wrong god doing it.

The groups are stratified, with one or more leaders and the rest as followers. This pattern continues even today, though the acquisition of language allows such groups to be institutionalized as tribes, armies, political parties, commercial empires, religious hierarchies, or sports teams. All of these have rules requiring defense and extension of territory by carrying some play object—a ball, flag, icon, trademark, or belief system—into someone else's territory. From the psychological point of view, there is very little difference between making religious converts, kicking the winning goal, or cornering the market on Thorbian gigarums.
"Proper gang activity requires the control of members. Gangs cannot tolerate 'loose' persons wandering around. One is either with the church or against it; with the company or against it; with the team or against it.

That is the god of jihad," she said. "That is the god of crusades. They are identical except for their names.
