Prove he isn't right, that is the game you like to play, so go right ahead.
Okay.
"Charity differences between religious and secular people persist if we look at the actual amounts of donations and volunteering. Indeed, measures of the dollars given and occasions volunteered per year produce a yawning gap between the groups.
The average annual giving among the religious is $2,210, whereas it is $642 among the secular. Similarly, religious people volunteer an average of 12 times per year, while secular people volunteer an average of 5.8 times. To put this into perspective,
religious people are 33 percent of the population but make 52 percent of donations and 45 percent of times volunteered. Secular people are 26 percent of the population but contribute 13 percent of the dollars and 17 percent of the times volunteered.
These differences hardly change when we consider them in isolation from the other demographics, using a statistical technique called tobit regression. Religious practice by itself is associated with $1,388 more given per year than we would expect to see from a secular person (with the same political views, income, education, age, race, and other characteristics), as well as with 6.5 more occasions of volunteering."

Secularists are stingy with their time and their money.
