An Evangelism movement borne out of post 60's boomer hedonism that promotes the self, and self fulfillment and a 'personal' relationship with God above all things, without standards? Surely some mistake.
Those definitely are defining features of the late 20th/early 21st century white* evangelical Protestant movement as a whole, but the kinds of evangelicals who are voting Trump (and honestly, some of those whom have voted Republican all this time - though many of the latter definitely have more obviously selfish economic reasons on account of their social class) put much more emphasis on not-so-subtle racism and sexism, nostalgia for the Confederate States of America and the pre-civil rights era, and aggressive nationalism.
These are the voters who are more "cultural" or "political" evangelicals - in that their (white) culture and (right-wing) politics trumps (no pun intended) their religious convictions (to the extent that they have any genuine or remotely consistent religious convictions). These are the voters who believe that Obama's Presidency is illegitimate and that the election is rigged against Trump. And if the opinion polls from the primaries are anything to go by, many of Trump's most hardcore white evangelical supporters aren't even reliable in terms of church attendance. So much for "consistency.."
*Note the
conspicuous absence of black, Latino, Asian, and other non-white evangelicals in this discussion. It's almost as if race is relevant here...
