This is good journalism, the type that invests in nuances, on an issue that seems cliché already. Everyone knows Trump and there have been guesses about what inspires his dangerous ideals. A few people have attempted to pitch a case on his mental constitution. This piece does it thoroughly. It also relates Trump's exuberance to the fears of white Christian evangelicals who wants to be saved from damnation (a.k.a ISIS), save the world (a.k.a America) from impurities (a.k.a Mexicans, immigrants etc.).
But more than this is how it explores the workings of Trump's mental makeup and how anger is the core of his personality.
Brilliant long piece.
"“As far as the anger is concerned, that’s real for sure. He’s not faking it,”... “The fact that he gets mad, that’s his personality.” Indeed, anger may be the operative emotion behind Trump’s high extroversion as well as his low agreeableness. Anger can fuel malice, but it can also motivate social dominance, stoking a desire to win the adoration of others. Combined with a considerable gift for humor (which may also be aggressive), anger lies at the heart of Trump’s charisma. And anger permeates his political rhetoric."
