Okay, in which case I'll respond to your points:
"Atheism requires no departure from logic or evidence, and therefore is logically supportable regardless of the thought processes of any individual or mental illness they may have (charming, by the way)."
Unrelated to my post, as I wasn't making a point about whether atheism was generally supported by logic and evidence.
"But again you are falling into the trap of trying to place atheism in a line with religions as an equivalent end point to arrive at, rather than the natural starting point."
No I'm not. I'm not trying to place atheism anywhere, just noting something that seems contradictory about some of the arguments made in this thread.
"No one knows anything about any religion or deity until they are told about it by another person, or they invent a belief system of their own."
While I generally agree with this point, I don't like the general tendency on this thread to assert that people are born believing or not believing X or Y. This is surely something to be determined empirically by developmental psychology, isn't it?
"No one has ever asked me to provide the rational justification for my lack of belief in ghosts or unicorns."
But presumably you can give one.
"Mostly they treat it as a natural state of being - given lack of evidence of their existence, I do not need to have made a rational decision not to believe in ghosts or unicorns."
But how did you come to the knowledge there is no evidence for ghosts or unicorns? Was that something you were born instinctively knowing? Or you were brought up to believe? Or is it something you've arrived at through your own reason?
Your assertion that there is no evidence implies that you have actually engaged in a rational assessment of the evidence, doesn't it?
"You missed quite a lot of nuance from your summation there. Intentional or just sloppy?"
I wasn't engaging in a summation. Why not try assuming I'm making a point in good faith instead of imagining I'm trying to engage in some kind of "gotcha" against atheism.
