it's akin to an atheist proudly proclaiming there is definitely no such thing as god
Almost feels like you supposed that to sound bad.
Yes because agnostic atheism is a logically superior belief system, that's much more intellectually honest and ironically: humble.
Aren't beliefs secondary guests in discussions about substance?
Edit: I'm not even a strict atheist if that matters much, but I wouldn't talk about it in assertive/provemewrong tone anywhere, cause it's not even remotely logical.
Atheism is such a weird position to take. Why define a negation of something you don't believe to be real? I'm not "a-lochnes-monster-ist" or "ayettist". If someone thinks the idea of a deity is nonsensical why then use the label "atheist"?
