When looking for commentary on trends in Gallup poll numbers about religion, it never hurts to do a few online searches and look for wisdom from the late George Gallup, Jr.

Reporters should also consider placing a call to John C. Green, a scholar and pollster who has followed trends in religion and politics for decades. Of course, it always helps to collect files of charts from political scientist Ryan Burge, a GetReligion contributor who is an omnipresent force on Twitter (and buy his latest book, “20 Myths about Religion and Politics in America”).

Gallup, Green and Burge (#DUH) played prominent roles in this week’s “Crossroads” podcast (CLICK HERE to tune that in), which focused on a Religion News Service story (via the Washington Post) about a now-familiar trend in America’s public square. That headline: “Poll: Americans’ belief in God is dropping.” The overture:

Belief in God has been one of the strongest, most reliable markers of the persistence of American religiosity over the years. But a new Gallup Poll suggests that may be changing.

In the latest Gallup Poll, belief in God dipped to 81 percent, down six percentage points from 2017, the lowest since Gallup first asked the question in 1944.

This raises an obvious question: Who is losing faith in God?

This news report links the trend to politics (#DUH, again) and makes a very interesting connection, in terms of cause and effect. Read this carefully:

Belief in God is correlated more closely with conservatism in the United States, and as the society’s ideological gap widens, it may be a contributor to growing polarization. The poll found that 72 percent of self-identified Democrats said they believed in God, compared with 92 percent of Republicans (with independents between at 81 percent).

In recent years there has been a rise in the number of Americans who acknowledge being Christian nationalists — those who believe Christian and American identities should be fused.

“It could be that the increase in the number of atheists is a direct result of Christian nationalism,” said Ryan Cragun, a sociologist at the University of Tampa who studies the nonreligious.

I’ll provide some additional details in the rest of the post to back up what I’m about to say. The big idea in this story, interpreting these latest Gallup numbers, appears to be this: Lots of young people in liberal and progressive forms of religion are so upset about the rise in vaguely defined Christian nationalism that they openly declaring that they are atheists and agnostics.

Say what?
