I believe that table about as much as I believe the one which listed states by iqs and who they voted for.
Church contributions are charitable. Does that make that table more believable?
In many parts of America, I would argue that money given to the Church is essentially paying for an institution through which people seek social engagement. Thus, it can be compared to the money people in less religious states spend on going out to eat and on the arts, going to concerts, etc.
In my view, having a market for social activities is far preferable than having social life monopolized by a church institution.
