Is atheism ever a faith?

[Edwardo Piet]

If, for example someone believes there is no God 100% and he has no (does not know any) evidence to support or dismiss his claim, isn't his atheism based on faith? And if this is true, despite the fact he believes 100% there is no God; isn't it possible that that is in fact quite a weak stance because if his belief is based on faith; which is based on preference and 'intuitive predictons' rather than evidence; couldn't he quite easily, atleast over time be converted to another faith? And therefore isn't his belief less strong than the 99% recurring belief - of the De Facto Atheist -against God because of evidence?

I believe I once had a faith in atheism for the sake of atheism and the sake of the vague intuitive likely hood I had of evolution, and for the sake of an anti-religious attitude. Also my belief was based on say the hatred of the God of the Old Testement and the Wars caused and finished by religion.

Now I have a belief (not a faith) in atheism that is entirely based on my belief in evidence. Also I still for moral reasons - that I thank for my genes and have developed through my memes and the conscious thought processes I have and the goals I have set -disagree on religion and hope to continue to argue against it in a verbal manner.
