This reads like the country-scale equivalent of "ALL heroes must have flawed! People aren't noble! It's unrealistic! That kind of character doesn't exist... nobody can identify with a character like that!"
This is the EXACT same logic that informed the
Man of Steel movie, which utterly rejected the premise that a hero can be aspirational. I reject it utterly. I prefer to once again recall the words of the late author (and professional a-hole) Harlan Ellison, who once wrote:
With only minor tweaking of verbiage, that could describe Wakanda too. Something that the world can aspire too... if not written by a writer whose only idea is to drag it down into the muck like the rest of the world.
In fact, Priest even SAYS as much, in a classic scene where Ross testifies about T'Challa to Congress:
Why is it that the worst sides of our nature are considered just "human beings", but people volunteering their time to help in a natural disaster, or running into a burning building to save a stranger, or flying halfway across the world to rescue a handful of kids in a flooded cave never are?
Why do people hate altruism, optimism, and nobility so damn much?
