The late Douglas Adams said the following in a speech, "Is there an Artificial God?" at Digital Biota 2, Cambridge U.K.
September 1998.

Now, the invention of the scientific method is, I'm sure we'll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and it rests on the premise that any idea is there to be attacked. If it withstands the attack then it lives to fight another day and if it doesn't withstand the attack then down it goes. Religion doesn't seem to work like that. It has certain ideas at the heart of it which we call sacred or holy or whatever. What it means is, "Here is an idea or a notion that you're not allowed to say anything bad about; you're just not. Why not? ' because you're not!" If somebody votes for a party that you don't agree with, you're free to argue about it as much as you like; everybody will have an argument but nobody feels aggrieved by it. If somebody thinks taxes should go up or down you are free to have an argument about it. But on the other hand if somebody says "I mustn't move a light switch on a Saturday," you say, "I respect that."

The odd thing is, even as I am saying that I am thinking "Is there an Orthodox Jew here who is going to be offended by the fact that I just said that?" But I wouldn't have thought, "Maybe there's somebody from the left wing or somebody from the right wing or somebody who subscribes to this view or the other in economics," when I was making the other points. I just think, "Fine, we have different opinions." But, the moment I say something that has something to do with somebody's (I'm going to stick my neck out here and say irrational) beliefs, then we all become terribly protective and terribly defensive and say "No, we don't attack that; that's an irrational belief but no, we respect it."

Why should it be that it's perfectly legitimate to support the Labour party or the Conservative party, Republicans or Democrats, this model of economics versus that, Macintosh instead of Windows ' but to have an opinion about how the Universe began, about who created the Universe... no, that's holy? What does that mean? Why do we ring-fence that for any other reason other than that we've just got used to doing so? There's no other reason at all, it's just one of those things that crept into being, and once that loop gets going it's very, very powerful. So, we are used to not challenging religious ideas but it's very interesting how much of a furore Richard creates when he does it! Everybody gets absolutely frantic about it because you're not allowed to say these things. Yet when you look at it rationally there is no reason why those ideas shouldn't be as open to debate as any other, except that we have agreed somehow between us that they shouldn't be.

I was motivated to post this by a discussion with a friend of mine. We were discussing whether or not a person's religion or lack thereof should be an acceptable factor in choosing who to vote for in an election. The fact of the matter is that it is used all the time, but the question is should it be? We decided that it didn't constitute an unacceptable form of discrimination because religion or lack thereof is a choice and ethnic background and maybe homosexuality are not choices. I maintain, though it is acceptable, it is a lazy man's way that is frought with danger.

So should an Atheist respect religon? No. Should a religious person necessarily respect Atheism? No. They should conduct a careful analysis of the claims made and come to a rational conclusion, not one based on an emotional outburst.
