I think the superfamous atheists (Dawkins, Hitchens et. al.) have claimed the term to mean "knowing there is no god". If people want to think something else they need to search for better terms that explain how they feel.

Like I've mentioned, I'm ignostic, I don't think the question is valid. This avoids all the epistemological problems of Dawkins' Atheism, as well as takes all religious arguments off the table. If you want your god to be part of the discussion then you need to provide me with a falsifiable experiment regarding god's existence. In short, I've moved the argument from an ontological to an epistemological one. I don't think the former can be won (by either side) and the latter makes the whole discussion irrelevant.
