"The wishful thinking stuff can work both ways. I recall hearing about Richard Dawkins actually saying one of the appeals of atheism is that it allowed him to screw around on his wife with the happy confidence of no afterlife repercussions."

That just means he's an asshole, not that he's thinking wishfully. I don't screw around on my wife, despite not fearing afterlife repercussions. Why? Well, for one thing, I fear repercussions in THIS life, and not just if I'm caught. I value our relationship highly, and I know from prior experience how toxic and worrisome such secrets can be, even if they're still secret.

The appeal of agnostic atheism for me is that it doesn't require me to suspend my disbelief and accept some bizarre hypothesis on faith. It doesn't purport to answer any unanswerable questions. That's appeal enough - not to mention, I simply find it impossible NOT to be an atheist.
