For me, personally:
Atheism describes my stance on the existence of gods. It’s not a positive belief or set of directives like a religion.
Secular Humanism describes my philosophy of life.
Naturalistic Pantheism describes my religion (though I’m pretty slack about it).
Evolution doesn’t much influence my religious beliefs. I’d still be an atheist if the theory of evolution imploded tomorrow (fat chance), and I didn’t have a problem with evolution when I was a theist.
I have a Cthulhu fish on my car, because I think it’s funny. I don’t particularly like Darwin fish, because it buys into the whole evolution vs. Christianity fallacy. I also have a “Happy Humanist.” Plus I had an “I believe in life before death” bumper sticker before someone wrecked my bumper.
I like to have this stuff on my car, and to mention my atheism when it comes up naturally, because I think it’s good for people to realize that atheists aren’t just elitist philosophy professors living in NYC or something. I’m pretty much just like my neighbors, except for this one thing. I’m a faithful wife and a stay-at-home mom. I’m moral, friendly, and generous. This does not fit with many people’s stereotypes of us.
I’m a raging civil libertarian, but I’m economically moderate, so I don’t fit any of the typical categories mentioned above.
In my view, most theists are as intelligent as atheists. IIRC, atheists do tend to have more education, but that doesn’t equate to IQ. Nevertheless, there is something different about atheists who have rejected religion - for some reason, we are able/willing to examine an area of belief that has been cordoned off from everyday rational inquiry in most people. For me, the trigger was my interest in urban legends and paranormal claims. Once I developed a standard of proof for such things, I realized I could also apply it to the gods question. It scared me a bit, but I felt obligated to do so, and then I realized there was no good reason to believe in any gods. I’m still open to more convincing evidence, but extremely doubtful it will appear.
As for Pascal’s Wager, I like to hypothesize a perverse god who rewards atheists for their rationality with heaven, while punishing the blind faith of theists with hell. There, Pascal, that’ll put marzipan in your pie plate, Bingo!
