Bill DeWitt is discussing:

A recent series of surveys found numerous areas of overlap in the morality of believers and the non-religious, but also distinguished key differences in terms of group identity versus individuality in guiding people’s morality.

The deceptive premise here is that religion is a behavior modification program.

Religion is about what God wants, why we are here, and what happens to us afterward. Man's "morality" has nothing to do with that. So basically this is an atheist setting up a strawman then bragging about how he defeated it.
