Stephen Bullivant presents evidence that the US is becoming an ex-Christian country, as more people become ‘nonverts’ to no religion.

Meet John: a serious, straitlaced, staunch libertarian. Economically and sartorially conservative, he panic-bought his AR-15 rifle in 2016 in fear of a looming Clinton repeal of the Second Amendment. Meet Judy: a proud, practising polyamorous progressive. Mohawk-ed and inked, she can normally be found either behind the bar she co-owns, or else officiating gay weddings as a state-approved “minister of religion”. I encountered both within the space of a few hours – Judy at a mall Starbucks, John at a gun range to try out that AR-15 – in the same mid-sized city that each calls home. It’s just a normal day in southern Louisiana.
