I just wanted to point out that these things are not mutually exclusive.VanTesla said:...religious believers, atheist, and agnostics...
Agnostic, despite what the general opinion is, does not mean "unsure of the existence of deities". Gnosticism has nothing to do with religion, inherently, but is rather a proclamation of knowledge.
Atheism is simply a lack of acceptance to theistic claims. It is not the opposite claim that gods do not exist.
There are effectively four kinds of people in the world, in regards to religious beliefs.
Agnostic Theist - Someone who believe there is a god or gods but claims no knowledge or proof of their existence.
Gnostic Theist - Someone who believe in a deity or deities and proclaims to know he/she/they exist.
Agnostic Atheist - Someone who is unsure if there are any deities, or someone who does not accept theistic claims, and claims no knowledge either way.
Gnostic Atheist - Someone who does believe deities exist and claims absolute knowledge of that claim.
Truth is, most people who call themselves agnostics are really Agnostic Atheists. Which is not a bad thing. Atheism isn't a dirty word. Religious indoctrination has turned it into one. Likewise, many religions followers are Agnostic Theists.
Anyway, I know this doesn't really address the points in your post, but I just wanted to clarify for everyone the misconceptions behind the terms.
