I've been on several threads now about defining atheism/agnosticism and you are the first person I have seen actually show ANY shift In understanding, or even openness to explanations other than the one they hold.
Most here (believers anyway) only try to attempt to "redefine" atheism as a positive "claim" that **** do NOT exist, thereby shifting the burden of proof onto those who in fact, just lack belief.
Many fail to understand (willfully?) when I explain to them that I am agnostic as well as atheist. I don't "know" (agnostic) if *** exists, but I do not "believe" that any **** do exist.
I do not see agnosticism as some non-committal, middle ground between theism and atheism, where people who can't decide hide, but many people do. For example when I describe myself as agnostic I often get comments that tell me believers think they have a chance of convincing me that **** exist, even though it is impossible for me to believe.
