Many of us saw religion as harmless nonsense. Beliefs might lack all supporting evidence but, we thought, if people needed a crutch for consolation, where's the harm? September 11th changed all that. Revealed faith is not harmless nonsense, it can be lethally dangerous nonsense. Dangerous because it gives people unshakeable confidence in their own righteousness. Dangerous because it gives them false courage to kill themselves, which automatically removes normal barriers to killing others. Dangerous because it teaches enmity to others labelled only by a difference of inherited tradition. And dangerous because we have all bought into a weird respect, which uniquely protects religion from normal criticism. Let's now stop being so damned respectful!

Belief in God's presence and action in American public life, in social events, in education, in civic celebrations and political discussions, which for two hundred years had been considered broadly beneficent, changed radically on September 11, 2001.

The danger of religious faith is that it allows otherwise normal human beings to reap the fruits of madness and consider them holy. Because each new generation of children is taught that religious propositions need not be justified in the way that all others must, civilization is still being besieged by the armies of the preposterous. We are, even now, killing ourselves over ancient literature. Who would have thought something so tragically absurd could be possible?

Like all "acts of terrorism" (easily and unsubjectively defined as organised violence against civilians), September 11 was an attack on morality: we felt a general deficit. Who, on September 10, was expecting by Christmastime to be reading unscandalised editorials in the Herald Tribune about the pros and cons of using torture on captured "enemy combatants"? Who expected Britain to renounce the doctrine of nuclear no-first-use? Terrorism undermines morality. Then, too, it undermines reason. … No, you wouldn't expect such a massive world-historical jolt, which will reverberate for centuries, to be effortlessly absorbed. But the suspicion remains that America is not behaving rationally — that America is behaving like someone still in shock.

My last vestige of "hands-off religion" respect disappeared in the smoke and choking dust of September 11, 2001, followed by the "National Day of Prayer", when prelates and pastors did their tremulous Martin Luther King impersonation and urged people of mutually incompatible faiths to hold hands, united in homage to the very force that caused the problem in the first place.

Religion is a by-product of fear. For much of human history it may have been a necessary evil, but why was it more evil than necessary? Isn’t killing people in the name of god a pretty good definition of insanity?

All religions look wacky to an unbeliever, even to one who does not, like the celebrity atheists, consider religion a menace. Islam, in its present frustrated state, is doing more harm than most, but that's historically contingent.

And yet people ask what's the harm of religion - and we cite all these different problems with religion: the global gag-rules and things like that , the oppression of different people - but there's a bigger harm with religion, and it's the reason why I'm outspoken about it, and that's because the average feel-good Johnny-in-the-pew person who is decent and kind and loving and good to their family and generally a good person to be around has polluted their mind to the point where they are unable to take credit for their accomplishments and responsibility for their actions. They are unable to interact on an interpersonal level with the people around them, to build a community in this cooperative society where that is absolutely essential. They have got this mentality that they are worthless without God.

None of us would ever wish the evil that was done on September the 11th. Yet after America was attacked, it was as if our entire country looked into a mirror and saw our better selves. We were reminded that we are citizens, with obligations to each other, to our country, and to history. We began to think less of the goods we can accumulate, and more about the good we can do.

Religion's greatest trick wasn't making some people believe there was a God, it was telling you you shouldn't ever ridicule the ide, that it was sacred, to question this dogma> And of course it's not. As a scieentist,philosopher and comic that is something that is really important to me. NOTHING is sacrad.

In the course of history it has often happened that one or other of the imperfect religions has been taken too seriously and regarded as good and true in itself, instead of as a means to the ultimate end of all religion. The effects of such mistakes are often disastrous.

"Religion, then, is far from "useless." It humanizes violence; it protects man from his own violence by taking it out of his hands, transforming it into a transcendent and ever-present danger to be kept in check by the appropriate rites appropriately observed and by a modest and prudent demeanor. Religious misinterpretation is a truly constructive force, for it purges man of the suspicions that would poison his existence if he were to remain conscious of the crisis as it actually took place.

To think religiously is to envision the city's destiny in terms of that violence whose mastery over man increases as man believes he has gained mastery over it. To think religiously (in the primitive sense) is to see violence as something superhuman, to be kept always at a distance and ultimately renounced. When the fearful adoration of this power begins to diminish and all distinctions begin to disappear, the ritual sacrifices lose their force; their potency is not longer recognized by the entire community. Each member tries to correct the situation individually, and none succeeds. The withering away of the transcendental influence means that there is no longer the slightest difference between a desire to save the city and unbridled ambition, between genuine piety and the desire to claim divine status for oneself. Everyone looks on a rival enterprise as evidence of blasphemous designs. Men set to quarreling about the gods, and their skepticism leads to a new sacrificial crisis that will appear - retrospectively, in the light of a new manifestation of unanimous violence - as a new act of divine intervention and divine revenge.

Men would not be able to shake loose the violence between them, to make of it a separate entity both sovereign and redemptory, without the surrogate victim. Also, violence itself offers a sort of respite, the fresh beginning of a cycle of ritual after a cycle of violence. Violence will come to an end only after it has had the last word and that word has

If your faith is threatened by something that’s true, then it wasn’t much of a faith to begin with, was it?

Religions have done far more damage over the centuries than good. Religion may help individuals to bear hard times and trouble and loss, but institutionalized religion of all stripes quickly becomes dangerous. Established religion always seems to breed a them vs us mentality that has lead to crusades, pogroms, ethnic cleansing, the Inquisition, genocide, civil war, and legal discrimination.
