@XXSpadeMasterXX,
I'm human, so I'm sure I have biases. Not all biases are bad, though. I prefer things that promote peace and understanding, rather than division and ignorance. In general, though, I don't feel much of an imperative to go out and change the world to conform to my preferences.
As for my particular take on atheism, I don't claim to know that there is no god, but I do now claim that I've never had a genuine, direct experience of a god, even though I used to believe that I was in direct, sometimes ecstatic contact with one. I used to be very deeply religious, a Christian, to the point that I was enrolled in university in order to become an Episcopal priest. While I was taking a class called "The History of the Bible," taught by a Baptist minister, it suddenly dawned on me that the parts about a supernatural deity and miracles was made up. I'm sure there are some historically factual parts of the Bible stories, but that doesn't mean that the main part, the existence of an invisible, all-powerful, supernatural, undetectable entity is true. A much more logical explanation is that a ruling-class theocracy made up stories and built on them over the centuries in order to control the gullible majority. Politics and power, in a nutshell.
So, I don't believe that there is a god, but I don't claim to know for sure that there isn't one. What I can claim is that I have never seen credible evidence for such a thing. Everything I've experienced, seen or heard about is more rationally explained by perfectly mundane means. I'm open to any new evidence that comes along, but I doubt there will be any.
Why? Because Christianity places so much value on faith. You have to believe without evidence. If you have evidence, you have knowledge, and therefore faith is destroyed. Therefore, Christians have a vested interest in not having real, credible evidence. The modern, scientifically literate mind, however, is trained to make judgements based on evidence, regardless of whether or not that conclusion feels good.
That said, as long as you're not strapping on a bomb vest or stoning girls for learning how to read, I'm not very interested in opposing you. You've got a right to lead your life as you see fit. Of course, if you come knocking on my door and trying to sell me your beliefs, then you're instigating the contact, so I'll feel free to oppose your ideas. But not you personally.
Is there a god? If I'm intellectually honest, I have to say, "I don't know for sure." But if you want me to donate 10% of my income, then you'll need to produce some evidence. If someone takes you to court and accuses you of having stolen something, you'd demand evidence, wouldn't you?
