While the psychological premises of the article are flawed, the writer is correct in comparing Donald Trump with historical he-men.
American men as a whole have not feminized. I think the episode on the Paris train has proven that.
We have, however, grown to equate confidence, standards of competency, and strength of conviction with mindlessness, bigotry, and buffoonery. Accomplishment is seen as something almost course and dirty, something to be delayed by regulations and impact studies.
Trump, more or less, stands for a return to the old dynamic.
