To go against the status-quo, particularly in the initial enthusiasm for the wars - and yes, if you go back and look at the polls, you'll see that the majority of Americans supported both the Afghanistan and Iraq war initially - means to give up the cushy life of the clergy, or at least to draw ire and scrutiny. What about their tax-exempt status! Bravery is not something most church leaders are known for, let alone for being Mavericks or iconoclasts - whether or not Jesus ever was such, or whether or not Jesus even existed, or is not, as most atheists believe, some cobbled together, ever-morphing myth of men (plural), and previous stories (with unbelievable miracles thrown in to keep things spicy).
Besides, torture has been part and parcel of the Christian religion since Christ was crucified. Actually, before that, since the Old Testament is full of human tortures visited upon the helpless minions of the various human races (Golden or not), by a vengeful, spiteful, twisted, spoiled, bratty, unpredictable, and all-hurtful God. Better not to bother with such a Being at all, in this atheist's opinion.
While Religionists hide behind comforting platitudes like "It's God's Will," or, it's useful corollary when the s*** hits the proverbial fan, "The Devil Made Me Do It," atheists have no such recourse. Perhaps that's why there are so few of us - though 12-18%, depending on the definition of various polls, is still larger than most religions. In any case, we atheists, when we act, due to circumstances beyond our control, or not, can only blame ourselves. The Devil/God is in us. We made us "do it." Perhaps that is the only way to take responsibility. Perhaps that is the only way to grow up, out of the sandbox of the Pew, where people play with moral principles with their religious toolset of Rosary beads to Bibles, as if they were plastic pails and shovels, and have only just as much influence over real-world affairs as a sandcastle in a sandbox. Of course, being stuck in a Pew means you are not free to get out and do some actual good work on your off-day. Hmmm, maybe the religious orthodoxy are not so dumb, after all.
Of course, this hedonistic impulse is as true of the atheist as of the religionist, but at least the atheist has made a step into the light, out of the shadow of an all-knowing, all-permission-granting, torturing, God.
