I've put some thought into this issue and have now decided to argue against your assertion that strong atheism requires faith. First of all, faith is associated with firm belief. Strong atheists believe that God does not exist. Theists typically have firm belief that God does exist.doom: And atheism is kinda like firm belief without logical proof,cos both ways there is no proof,and as you say an atheist is not absolute 100%,but they are like the believers in that its close to that absolute and may act like there 100%.
Jade Squirrel: I see the point you are making. It seems like you are referring to strong atheism, which is belief that there is no God. Weak atheism, on the other hand, is simply lack of belief that God exists. Note that there is a significant difference between the two. I can see how you would think that strong atheists have faith that God doesn't exist. Since I prefer weak atheism, I feel no need to argue for or against that point.
Also, strong atheism is not faith because faith is belief without proof. There is some evidence to support strong atheism, albeit weak atheism is easiest to defend. First, a lack of any evidence, especially given that many theists constantly try to prove the existence of God, is evidence in itself. Add to that the almost universal human tendency to anthropomorphize. Then there's the logical contradictions that are inherent in the concept of an omnipotent creator.
I will admit that this is not conclusive proof, and such proof will in all probability never be obtained. But the strong atheistic perspective is scientific in that it uses the existing evidence to form the most likely hypothesis: God does not exist. It is scientific because it is a falsifiable statement. Simply show that God exists and the theory must be abandoned. The statement that God does exist is not scientific because there is no good evidence to indicate this, and the statement is not falsifiable.
Hmm... I seem to have now talked myself into preferring strong atheism.
