A question about defining 'Atheist'

[orangebox21]

There is a bit of confusion for myself as a theist in trying to understand the definition of atheism. I've seen a few assertions throughout various threads and I have a few statement/questions for clarification.

1. I've heard some say it's not that the atheist has a belief in no-god, but rather a rejection of the proposition that God exists. How are these two positions different?

2. If an atheist accepts that there is a difference between rejecting the belief in the existence of deities and asserting they do not exist (asserting the former not the latter), does that differ from the assertion that God does exist, but he/she rejects belief in God?

3. If you assume the reliability of the law of the excluded middle, then logically speaking there are only two possibilities: God exists or God does not exist. By definition, there cannot be 'maybe God exists.' (I want to clarify here that I'm not proposing a person can't be in a process of inquiry where they are testing the truth of one or both of these propositions and so are 'wondering if God exists', but rather there is no logical conclusion that 'maybe God exists') Given only two possibilities, is assigning a truth value to the proposition 'God exists' of false, does that necessitate assigning a 'true' truth values to the proposition 'God does not exist'? In other words, if you reject the propostion 'God exists' does that necessitate you conclude the proposition 'God does not exist'?

4. Also involving the law of excluded middle, is the position of 'agnostic' (maybe there is a God) logically sound?

5. Does the law of excluded middle allow for a neutral position (maybe God exists) with which to begin logical inquiry?

6. It seems that the rejection of the proposition 'God exists' is a postion the atheist takes. If you reject the proposition that 'God exists' are you required to defend this position?

7. If I as a theist were to reject the proposition that 'there is no-god', would I have to defend this position?

8. Atheism is to Biblical Christianity as agnosticism is to deism. Is this an accurate relation of terms?

9. What label would you prefer to describe your worldview/religion? Please provide a definition and/or brief explanation.

Thanks in advance to those who participate.
