n-1) Me, as I don't like someone telling me I'm an atheist because I don't believe in any god when I also don't believe that there isn't any, particularly when this is done via claiming that certain definition (which even dictionaries don't reflect) is correct and based on the "logic" that because atheism is a "lack of belief" rather the epistemic position it is, therefore anybody who doesn't believe in god has the same (atheist) position that someone who believes there is no god (or that there can be those who "lack belief" in god yet are able to identify themselves as atheists or use the word god).
n) People who are concerned with the atheist intellectual tradition being dumbed down by illogical attempts at defining it as a default position, choosing to define their position as somehow the automatically "right" one or "default" such that they need not engage in the arguments and intellectual feats that drove religious debate and culture itself forward thanks to a lack of such simplistic cowardice.
