“Name me an ethical statement made or an action performed by a believer that could not have been made or performed by a non-believer.”
Believe it or not, I hadn't come across this until JDawg and Arioch recently posed it to me. Since neither has bothered to respond to my answer of this challenge, I decided I'd post it for others to comment on and critique. Here's my answer:
"A non-believer could not honestly affirm the moral basis of anyone who believes morality to be revealed by a god. All an unbeliever can do is to assert that the believer has no "real" basis for such morality, whereas the believer can affirm the morality of a non-believer, based as it is on reasoning they could honestly agree with.
It is immoral to undermine the basis of someone's existing morality, thus encouraging immorality."

I realize that many answers have been proposed which Hitchens wouldn't have acknowledged as valid. This one is completely by definition. This challenge assumes that a non-believer subscribes to some morality or ethical conduct. By any definition of these, undermining the grounds of another person's ethics is, itself, unethical.
