I agree will you except for one little phrase: “Though scientists haven’t yet figured out why Trump does what he does.” Not true at all. FBI and CIA profilers and anyone who has ever throughly read the The True Believer by Eric Hoffer easily understands the goings on in the mind of Trump and his fanatical followers.
In fact Trump’s base psychology has been painted in graphic detail countless times. He is a pure egocentric personality totally lacking in intellectual modification — a cunning, selfish child at heart, being undisturbed by dire consequences of his actions. New York Times columnist, Divid Brooks, wrote a wonderful editorial laying out the childish mind of Donald Trump.
Like Hitler Trump is a connoisseur of primitive ego emotion and the negative tribal impulse springing from it among large swaths of the world’s citizenry, an impulse that he has made a career out of manipulate to suit his own infantile ends.
