This is certainly true of some atheists I have known. My ex-husband claimed jokingly to have an adversarial relationship with God. He was irritated at anyone, even God, suggesting that the profligate, licentious way he conducted his life was wrong—he rejected the concept of “wrong” because it limited his ability to indulge himself. So he merely denied the existence of God. (Later, fortunately, he learned how mistaken he was.)
On the other hand I know a very gracious, gentle, joyful, wise woman who is an atheist. It’s hard to believe she’s not full of the Holy Spirit; she’s so happy and such a joy.
The camp should be divided into two groups, atheists and antitheists. People like Dawkins and Hitchens fall into the antitheist wing. That wing seems to be a lot larger than the atheist wing, by the way.
An atheist may be wise about some things, but their wisdom just can’t be very deep as they are missing the very foundation of all existence.
