You've said that nonbelievers must try to convince religious people "of the illegitimacy of their core beliefs." Why are these beliefs dangerous?
On the subject of religious belief, we relax standards of reasonableness and evidence that we rely on in every other area of our lives. We relax so totally that people believe the most ludicrous propositions, and are willing to organize their lives around them. Propositions like "Jesus is going to come back in the next fifty years and rectify every problem that human beings create"--or, in the Muslim world, "death in the right circumstances leads directly to Paradise." These beliefs are not very contaminated with good evidence.
There are beliefs--like kids believing in the tooth fairy--that I wouldn't say are dangerous.
Right. Those are not as consequential. But this whole style of believing and talking about beliefs leaves us powerless to overcome our differences from one another. We have Christians against Muslims against Jews, and no matter how liberal your theology, merely identifying yourself as a Christian or a Jew lends tacit validity to this status quo. People have morally identified with a subset of humanity rather than with humanity as a whole.
You're saying we should be part of the human race, not part of any particular religious or national group?
Yeah. It is still fashionable to believe that how you organize yourself religiously in this life may matter for eternity. Unless we can erode the prestige of that kind of thinking, we're not going to be able to undermine these divisions in our world.
To speak specifically of our problem with the Muslim world, we are meandering into a genuine clash of civilizations, and we're deluding ourselves with euphemisms. We're talking about Islam being a religion of peace that's been hijacked by extremists. If ever there were a religion that's not a religion of peace, it is Islam.
If 9/11 hadn't happened, what would be the example atheists would point to--another egregious, contemporary misuse of religion?
There are so many. Let's take the extreme case, honor killing in the Muslim world. Imagine the psychology of a man who, upon hearing that his daughter was raped, is inspired not to console her, not to seek immediate medical and psychological treatment for her, but to kill her. This is an honor-based, shame-based psychology. You cannot name a Muslim country to my knowledge where it doesn't happen. It even happens in the suburbs of Paris. It falls right out of the theology of Islam.
What are some problems with Judaism and Christianity?
There is no text more barbaric than the Old Testament of the Bible--books like Deuteronomy and Leviticus and Exodus. The Qur'an pales in comparison.
Richard Dawkins, a vocal atheist, has said the Old Testament God is a "psychotic monster."
Not only is the character of God diabolical in those books, but there are explicit prescriptions for how to live that are not metaphors; they are not open to theological judo. God just comes right out and says "stone people" for a list of offenses so preposterous and all-encompassing that the killing never stops. You have to kill people for working on the Sabbath. You kill people for fornication.
That's the point: in the West, we have delivered the salt. Obviously, people are no longer burning heretics alive in our public squares and that's a good thing. We in the West have suffered a sufficient confrontation with modernity, secular politics, and scientific culture so that even fundamentalist Christians and Orthodox Jews can't really live by the letter of their religious texts.
We now cherry-pick the good parts. That's easier to do with the Bible because the Bible is such a big book and it's so self-contradictory; you can use parts of it to repudiate other parts of it. Unfortunately, the Qur'an is a much shorter and more unified message.
