Yea by definition I would be an agnostic atheist but I don't think I would identify my self with what I don't know and what I don't believe in. By definition I think Buddhist would be atheist but we all know what Buddhist believe in.
So to my fellow non believers do you think it's weird to identify yourself with a non belief? why not Identify are selves with what we believe in but that positive belief just happens to not include a God/Deity .
The words "existential nihilism" don't jive with too many people...
