Is Atheism a Faith?

An atheist would he say he believes there is no god.A believer would he say he believes there is a god.Since there is no firm evidence that there is no deity, atheism is a belief, and a form of faith.The only truly rational position being agnosticism. Correct?

Incorrect. It is true that any kind of a belief system requires a prioris. Your question implies several-- that belief is a form of faith, that rationality relates to one's world view, and that evidence and should inform one's world views. Furthermore, your question implies that there are but three categories of "belief"-- theism, atheism, and agnosticism. Another category also exists, that such categories are themselves meaningless. The term A.J. Ayer used for this was acognosticism.

I have my doubts that people who call themselves atheists or theists can engage is a civil exchange of arguments, because such conversations rarely get past radically different phenomenal/noumenal epistomological presuppositions and god-definitions that shapes subsequent arguments.
