Every person who believes in something without evidence, just because they want to, legitimises that approach for everyone else who wants to believe without evidence. By accepting that religion is an acceptable form of thought, you are contributing, just a little, to the insane excesses of religious violence in Pakistan, in Iraq and Afghanistan: to bans on the use of condoms in countries that are suffering AIDS epidemics; to male Jewish babies being savagely mutilated in the first few months of life; to children in the US dying because they are being prayed for instead of being given medical attention; to abortion clinics being bombed and legal abortionists murdered.
All this happens because someone, somewhere, thinks it's all right to believe in something without evidence. And as long as you believe in something without evidence, then there is no way you can honestly criticise them. You believe you are following the commands of your God; so does Osama Bin Laden. You are, no doubt, genuinely sorry when other people get hurt because they are in the way of those commands; so is Osama. But what you perceive as the commands of God take precedence for you over the ordinary dictates of human conscience and common sense; just as they do for Osama.
Richard Dawkins can legitimately tell Osama how and why he is evil and wrong; you can't, because morally you and Osama Bin Laden are equivalent. Your god happens to be less confident and more conciliatory than his, because your god has been on the losing end of a five-hundred-year-long fight with science and reason, and his has only just begun to fight. But while you are both prepared to do senseless, unreasonable things just because you think your god wants you to, then there's not a hair's-breadth of moral difference between you.
Show respect for religion? Hells no.
