Is religion really at fault?

After Sam Harris presents an argument against the Christian Bible (although isn't it actually the Old Testament?) to write laws, he blames the Koran for terrorism:

President Bush and the Republicans in the Senate have failed — for the moment — to bring the Constitution into conformity with Judeo-Christian teachings. But even if they had passed a bill calling for a constitutional ban on gay marriage, that would have been only a beginning.

Leviticus 20:13 and the New Testament book of Romans reveal that the God of the Bible doesn't merely disapprove of homosexuality; he specifically says homosexuals should be killed: "If a man lies with a male as with a woman, both of them have committed an abomination; they shall be put to death."

God also instructs us to murder people who work on the Sabbath, along with adulterers and children who curse their parents. While they're at it, members of Congress might want to reconsider the 13th Amendment, because it turns out that God approves of slavery — unless a master beats his slave so severely that he loses an eye or teeth, in which case Exodus 21 tells us he must be freed.

What should we conclude from all this? That whatever their import to people of faith, ancient religious texts shouldn't form the basis of social policy in the 21st century. The Bible was written at a time when people thought the Earth was flat, when the wheelbarrow was high tech. Are its teachings applicable to the challenges we now face as a global civilization?...

Of course, the Bible is not the only ancient text that casts a shadow over the present. A social policy based on the Koran poses even greater dangers. Koran 9:123 tells us it is the duty of every Muslim man to "make war on the infidels who dwell around you." Osama bin Laden may be despicable, but it is hard to argue that he isn't acting in accord with at least some of the teachings of the Koran. It is true that most Muslims seem inclined to ignore the Koran's solicitations to martyrdom and jihad, but we cannot overlook the fact that some are not so inclined and that some of them murder innocent people for religious reasons.

The phrase "the war on terrorism" is a dangerous euphemism that obscures the true cause of our troubles, because we are currently at war with precisely a vision of life presented to Muslims in the Koran. Anyone who reads this text will find non-Muslims vilified on nearly every page. How can we possibly expect devout Muslims to happily share power with "the friends of Satan"? Why did 19 well-educated, middle-class men trade their lives for the privilege of killing thousands of our neighbors? Because they believed, on the authority of the Koran, that they would go straight to paradise for doing so. It is rare to find the behavior of human beings so easily explained. And yet, many of us are reluctant to accept this explanation.

Religious faith is always, and everywhere, exonerated. It is now taboo in every corner of our culture to criticize a person's religious beliefs. Consequently, we are unable to even name, much less oppose, one of the most pervasive causes of human conflict. And the fact that there are very real and consequential differences between the major religious traditions is simply never discussed.

As a non-believer I'm annoyed by the gullibility and irrationality of religious believers, but they don't have a monopoly on those qualities. Yes, they sometimes outrightly inflict harm. But on the whole they're harmless, and frequently do a lot of good. Besides, it's only a small minority of religious believers that engage in this kind of behavior. I think religion is just a tool populist rabble-rousers like to use against their enemies. Consider, for example, ethnic conflicts, which often little or no religious element.

In the eyes of most of the civilized world, the United States is now a rogue power — imperialist, inarticulate and retrograde in its religiosity. Our erstwhile allies are right not to trust our judgment. We elect leaders who squander time and money on issues like gay marriage, Janet Jackson's anatomy, Howard Stern's obscenities, marijuana use and a dozen other trifles lying at the heart of the Christian social agenda, while potentially catastrophic problems like nuclear proliferation and climate change go unresolved.

Good luck with that, given the standing of atheism in the US.
