When you get right down to it, "Atheist" is a stupid word.

[Pope George Ringo II]

37. There's at least one poster here who spectacularly fails to grasp what it means.

He does so in a way which I find quite incompatible with integrity, and crams his nonsense down everybody's throat in an appallingly rude display at every opportunity. It's simply inexcusable. At any rate, his determination to fail to know what it means suggests you might want to reconsider the usefulness of the term when dealing with such individuals.

But granting Maher's point about religion as a mental illness, most mental health providers will struggle to come up with much more than something like "reasonably normal" or "very functional" or some such as a description for somebody without a mental health diagnosis. A one-word term for the absence of an impairment is not really part of the lexicon.

But we have to have a specific word for somebody who doesn't believe in 4,200 constructs, instead of 4,199 or so.
