Is atheism a belief?

[Alan V]

Your version, their version.  That's why I don't put a special value on any of the claims because it has evolved into a new category with multiple "atheisms"  A NY Times Best Selling author.  Wonder who's buying.  Probably a mix of people with different beliefs.

The author is likely equivocating. Some atheists believe that "God" is a useful concept socially. I doubt they believe in an actually existing God, and if they do they are not atheists by definition.

This is not about my version or their version. It's about parsing dictionary definitions.
