...that's your opinion, though. A believer in fairies (or unicorns, or the FSM, whatever) may have the opposite opinion. You can only say it is an opinion, because there is no objective truth in the relative importance of each belief - because they are relatively different in importance, depending on whether you believe in it/them or not.
My point is the entire opposite of this though. I am claiming that the implications of Gods existence are equally important to the believer and non-believer alike. Their belief in God is not what is at issue. Rather the implications of Gods existence is what is at stake (regardless of what they believe in regard to his existence).
For example, suppose a bank has allegedly been robbed. There is a dispute over whether the bank has been robbed or whether they had no money to start with. I would argue that despite what people believe (in regard to whether the bank had money or not) this does not change the implications of what it means if the bank has actually been robbed and they did have money. The implications of genuine robbery are just as relevant for both debaters even if they disagree on whether the bank has been robbed or not. They are two separate issues.
In this same way, I would argue that the implications of Gods non-existence are just as relevant for believers and non-believers regardless of whether they personally believe God exists.
Well it's two things, I guess. One, I haven't seen any convincing arguments for theism, just as (continuing my analogy), I haven't seen any convincing arguments for fairies. The other is that my "negative" position is a default position, one that didn't "come to pass" but instead has always been there. I've never believed in fairies; I've never believed in God; I've never believed in monsters under my bed. Like all supernatural occurances (and most things I guess), non-belief is the logical default position, because (epistemically) we can never know for sure of their existence (given their supernatuality).
Suppose this is the default position (I say suppose because I don't know whether non-belief really is the default position), I don't see how this takes you beyond agnosticism. You have demonstrated a lack of belief, but you have not gone any way to affirming that God does not exist. At best I think this reasoning affords you a sort of weak atheism.
Also, I would like to add that I agree with you that scientific method can never be used to give proof of a supernatural entity - since the natural cannot test the supernatural. However, I would like to say that I think scientific findings combined with philosophy can make some headway in affirming or dis-affirming the existence of God. Also, you have to contend with personal revelation or experience. This, for that individual could (I think) properly be recognized as proof of God.
Lol, equating a mathematical truth to what you're saying is a misstep on your part, given mathematics has objective proofs and God does not
The mathematical example was done on purpose to show that opinion doesn't necessitate the falsity of a claim. I could have also said "Rape is wrong" or "Kevin Rudd won the 2008 election". The point is the same. That is, demonstrating that a person has an opinion does not show that their opinion is not true or false.
I have no idea what you're going on about when you refer to the genetic fallacy, by the way. I'm just responding to what you're telling me.
The genetic fallacy is the fallacy that argues that a belief is mistaken or false because of the way that belief originated. For example:
John: "Democracy is the best form of government"
Bill: "Oh you only say that because you were born in Australia"
How or why a belief came to be held is simply irrelevant to the truth or falsity of the proposition that is the object of that belief.
