And my challenge is this: "Can you name me a good action done or a good thing done by a believer that couldn't have been said or done by a non-believer?" I've offered this challenge now in print hundreds of times, and on the air, and on the Web, and in public, debating with quite senior religious people. None of them have come up with an example. Whereas, if I say in front of any audience you can think of, "Can you think of a wicked thing said or an evil thing done by someone because of their religious faith?" Nobody needs you to get to the end of the sentence, they've already thought of an example.
