The two are not mutually exclusive, you can be an atheist or theist agnostic, but also a positive or negative atheist.
You probably mean the colloquial use of agnostic fornegative atheist - the position of someone who does not believe that a god/supernatural being exists -, in contrast to positive atheism, the position of someone who believes that there is no god/supernatural being.
There is no problem with this colloquial use, I just wanted to clarify that the "professional" terminology does not match it.
I was just quoting someone else's use, I didn't really mean anything by it.
I've read about Anthony Flew's framework, but it still seems like unnecessary architecture to me, since I still haven't encountered situations where lay terms fail to describe someone's position in a reasonable way.
But you know, come to think, if there's one thing religion has taught me-- people can self describe however they like, and there's no sense fighting them on it. If people want to be called just plain atheists, or negative atheists, or double plus agnostics, or pastafarians, that's fine, I can go with whatever everybody's preference is.
