I'm not saying practical success by Christians is bad for others (and I didn't mean to talk of Christians and atheists as opposing teams); just nowhere close to being as good for others as practical success by well-informed (partial) utilitarians. I was taking Christianity as evidence that he failed harder at trying to be well-informed than many people, but that was probably unfair as I don't know anything about him. I should have brought up the point in a different context.
