My personal attitude toward atheists is the same attitude that I have toward Christians, and would be governed by a very orthodox text: "By their fruits shall ye know them." I wouldn't judge a man by the presuppositions of his life, but only by the fruits of his life. And the fruits - the relevant fruits - are, I'd say, a sense of charity, a sense of proportion, a sense of justice. And whether the man is an atheist or a Christian, I would judge him by his fruits, and I have therefore many agnostic friends.
