This may seem like a minor point, but can we please get away from the term "non-believer"? While it may be convenient shorthand, it suggests that non-religious or atheist people (two groups often conflated in the popular media) don't have moral beliefs. Perhaps more significantly, the term suggests that there is a god but that "non-believers" don't believe in that god, putting non-religious and atheist people in one group and ALL believers in another.
I would expect the producers of On Being (who I respect and admire greatly) to (a) understand that people who self-identify as non-religious or atheist often (though not always) hold deep moral convictions about their lives and the world around them and (b) be a little more nuanced with the language of belief systems than the average journalist.
