This is completely false. There are traditions within the theistic world that reject the notion that God is knowable rationally altogether, such as versions of religious existentialism.
And that somehow absolves them of their burden of proof??
Those who do not think that theism is rationally justifiable do not automatically become atheists--they could as easily be fideists, and this means there has to be some underlying reason behind why someone is an atheist or a fideistic theist. Neither of the two is a psychological default position.
The default position for claims of existance, is always disbelief until one is sufficiently convinced of the accuracy of the claim.
Or do you by default always assume that everything claimed is accurate?
It's either one or the other. You either think a claim is true or you don't.
You either answer "yes" to the question "do you believe x exists?" or you don't.
"yes" means that you accept the claim that X exists as true. Any other answer means that you don't accept that claim as a true-ism.
You're simplifying things to an extreme
I happen to think it's rather simple.
I'ld rather say that you are over complicating things.
, and I would imagine that very few people, theist and atheist alike, fit into the narrow categories you've devised.
I'ld say that they would have to be necessecity.
You either believe a claim is true or you don't.
Agreed, but a debate has two sides. If the atheist wishes to debate as well, the atheist must justify his position also.
You don't seem to be getting it.
The subject of debate here, is the postive theistic claim "a god exists".
The theist is the one that makes that claim. It is thus the theist that has to bring his case.
The atheist in this, is not making a claim. He's
responding to a claim and the reasons given by the theist for why one should believe said claim.
A "defense" of the atheist will necessarily consist of addressing those reasons, given by the theist. He can explain why he considers those reasons insufficient to believe. The ball is necessarily in the court of the theist. The theist first needs to bring his rationale / case / reasons for belief. The atheist can then address those reasons.
But the atheist position, in and of itself, is not a claim.
If the atheist wishes to sit in judgment and contribute nothing, then the atheist is being a narcissist.
No. Then the atheist is just
responding to a claim.
Consider alien abductees. It's upto them to bring their case for why it should be believed that they were abducted by aliens. We can then look at that case and address the proposed evidence, followed by a conclusion/position concerning their claim, based on a judgement of said evidence.
I'm going to skip the rest of your reply, since I can't multi-quote efficiently from the phone and won't have access to a computer for another week or so. If you'd actually like to discuss something here, please don't break the post up into small pieces like this, since even if I could reply to it, it's not exactly conducive to conversation.
I think it's very conducive for conversation as it allows me to address the various points directly.
But I know that I can exaggerate with it sometimes. Sorry
