"Donald Trump is religiously detached. In current parlance, he will enter the White House as a “none,” placing him in a rapidly growing number of Americans who don’t belong to a house of worship or subscribe to a particular creed."

Donald Trump has a church: his own ego.  Not only does he worship there, but he expects every American to worship his ego, too.  He is the Pontifex Maximus of his church, and, like the Roman emperors before him, he believes people who do not worship there are traitors.
