I've got a bad feeling about the direction this is going.
I agree with you, Andy, only in the sense that people who think they are smarter than others are frustrating. Well, I guess we all feel that way sometimes, so let me rephrase as "People who think they are smarter than others - even after deep introspection on the likelihood of that - are frustrating." But to pin that quality to all atheists - to make that quality a necessary trait of atheists - is unfair. You may assume all atheists are like that because those are the most vocal atheists!
For the record, not all atheists think they are smarter than those who believe in a god or gods; just as not all Christians try to convert, not all Jews are kosher, and not all Hindus take the Ramayana to be a true story. I am an atheist and have nothing but the utmost respect for my family members who believe in god. My mother-in-law, who was born again, welcomed me into her family even though I was raised Jewish. We used to have respectful discussions about everything. She never gave me grief for being Jewish (I did not tell her about my atheism because I knew how sad it would make her), she never proselytized, and I never questioned her being born again. It brought her joy and she felt it deeply, and that made me happy for her.
If anything, I feel envy. My wife's view of the universe is so much more spiritual and poetic than mine.
