God-Fearing Atheists

The study detailed Americans' deep and broad religiosity, finding that 92 percent believe in God or a universal spirit -- including one in five of those who call themselves atheists.

Which means that one in five atheists don't know what the word atheist means.

This might not be all that abnormal. I'll bet there's a percentage of any given group, made up of self-identified members, which has a basic misunderstanding of what actually defines the group.
