Something I have noticed, and it's just an observation and may not be correct, but I feel that more atheists tend to have a chip on their shoulders than agnostics. It seems that because 'Mom sent me to Catholic school' or 'Bible-thumpin' George W. Bush started a crusade against Islam' or 'Evangelicals won't accept homosexuality as an alternative lifestyle,' therefore 'because I disagree with what some religious individuals have done to ruin my life or poison the world, God cannot possibly exist.' One may use this as evidence in their personal quiver, but still cannot actually disprove God. They may only support their theory, but they cannot 'know' that God does not exist.

I think that many who are atheist are atheist with regards to a specific god of a specific religion. For example, Douglass Adams began his journey to atheism when he heard a street preacher and realized that the preacher was not making logical sense. This specific atheism is then often generalized to ALL religion, or else the distinction is rarely made clear.

I think that when many people claim to be atheist, they are simply saying that they have examined the evidence for a god of the religion of their parents/country and found this deity to have contradictory attributes. For example, how can the Christian God claim to be completely loving and also jealous, knowing that the Bible states that love is not jealous? In breaking strongly from such a deity, they claim atheism, as it is simply more applicable in most situations to their true feelings on the subject.
