Read Paul Johnson's "Intellectuals" and look at the atheists that you know. It's one long rationalization for personal misconduct.
Or look at it another way. It's a fact that people who attend Church regularly live on average 7 years longer than those who don't. Now this can be explained in one of two ways. Either there is a God and He generally rewards those who seek Him with longer lives, or Churchgoers are healthier because they refrain from unhealthy vices; i.e., they generally lead more virtuous lives.
The same asinine remark has been said of Christians "excusing" personal misconduct. People frequently get a little too exited when they first learn to spot hypocrisy and over generalize it to all members of competing ideologies.
"people who attend Church regularly live on average 7 years longer than those who don't. Now this can be explained in one of two ways."
I think the starts that I heard on Dr. Larua were regarding something more general than Church attendance, something along the lines of a strong believe system. That does not require a theological base.
