The old saying "no atheist in the foxholes" is an accurate assessment of the psychological conditions of soft core atheists. It's convenient to not worry about the after life if real life offers a variety of sinful excesses but when the manure hits the rotary blades who 'ya gonna call? You can bet your fragile asses that you are going to call on the big "G" of your choice.
I was an atheist in foxholes and a wounded combat vet. Not once did I callout in any way to any divine spirit.
