Since there is no God to hand down morality and punish you for disagreeing everything is up for debate and only a persuasive argument will work.
Maybe that's the ideal. But this is the web, so much atheist rhetoric boils down to "You're not in my club, so you're a fucktard. Now, join my club, or else I'll call you a fucktard again!" That didn't work on some of us, even in grade school.
Having said that, I'll also admit having slid from a solid 2 on the Dawkins scale to roughly a 5.6 over the past couple of years, due largely to the atheists I deal with IRL having better evidence and more compelling logic than the "sophisticated" theologians (let alone the (selective) scriptural literalisits).
Oh, and a lot of Dawkins, with a bit of Stenger. BTW, I find Dawkins considerably less militant than his reputation would suggest. Either that, or I just define "militant" much too tightly.
