> it is certainly defamation to ascribe specific pejorative acts to people when they never actually acted in that way
Except nothing in the cargo cult story is pejorative?
I mean, is it pejorative that ancient people worshipped the Sun as a God for bringing light and warmth to the world, not understanding what the Sun actually is? Religions were developed following that belief too.
I fail to see how it defames anything. Maybe the prejudice is in the eye of the observer in this case. Your disrespect for more primitive cultures makes you think their presumed behavior is detrimental to their intelligence.
> false narrative about an entire group or class of people, no?
First of all, it is not entirely clear that the story never happened. The accounts of cargo cults are disputed. I am simply giving it the benefit of doubt that the story may be apocryphal.
Second, the story does not paint a false narrative of anything. It just describes primitive cultures as primitive. Being primitive is not pejorative, it is merely descriptive. If you think it is pejorative, I suggest you spend some time reflecting on your prejudices.
> And regardless of that, how can a story describe human behavior if the story doesn't describe behavior that actually happened?
Have you ever read any fairy tale or old folktales? "The boy that called wolf"? "The emperor's new clothes"?
Perhaps you did not know, but those stories are fiction. Fictional stories can still contain allegories and insights on human behavior.
A weird notion, I know. The world is full of things like that.
