Dumbing down
I mentioned a while back that Christopher Hitchens seems to have a better grasp on what Christianity is than do a fair number of "Christians".
Here's another related comment on current beliefs from Susan Jacoby from a Washington Post debate in which she argued that 'religion' has a negative effect on society:
I think that in America, organized religion has lost ground to a flabby "spirituality" that makes no real demands on people. As a secularist, I see this amorphous spirituality as another sign of the dumbing down of popular culture. No demands, no history, nothing except what you personally feel at a given moment.
