There is a big problem with fiction: diversity is all but nonexistent. There are tokens galore, but when you use a Patriarchal structure, you exclude all but the One. When publishers and TV and movie studios do try to be "diverse," often the results are short lived and often offensively disastrous.
Case in point: the reboot of Ghostbusters was supposed to bring modern day sensibilities with an all-female cast. Great.
But the trailer reveals a very depressing truth: there is only ONE black lead, and she is delegated to being the street smart one while the three white women are the educated ones.
As a feminist, I demand equality for women of all colours, shapes, ages, religions, sexual orientations, political stripes, nationalities, and socioeconomic status. I happen to like Lesley Jones and will stay up late to watch her antics on Saturday Night Live, but she could have been the tough as nails one with the graduate degree. It is offensive and you can be sure I will sit this one out.
But the patriarchal is about the universe having a massive shortage of right answers and a right way to solve problems. It is also about mass idiocy to the point that everyone's elses's ideas except the hero's will fail, either because it is tinged with evil (and thus, is a villain), is inferior on an intellectual and moral level (and is then relegated to supporting cast), or non-existent and requires someone to bail them out (cue in the victim, or if it is a collective, cannon fodder).
That means the story structure itself is built in with the inherent assumption there can be no diversity because there is only the The One Right Answer That Solves Everything. Diversity is a nice theory in the world of the patriarchal, but it cannot exist in its reality. At the end, there is only The One who must intervene to prop up the weaker supporting cast who would flounder without him.
The matriarchal has no such rigged bias. The hero has a mighty supporting cast of equals. They may see the world differently, but they always come together using their collective skills, assets, thinking patterns, resources, knowledge, and ideas to solve a problem.
In this case, the matriarchal thrives in diversity. If everyone's meaning of life is different, then the collective means we each have a different role to play in overcoming obstacles.
We have relied on the patriarchal for so long, we assume that is the only right way to tell a story, and any deviation from the script is wrong, unprofessional, stupid, and bad. There is no room to progress and experiment, making the patriarchal a toxic system of storytelling.
Yet there are many ways to tell fables, from the epistolary to the matriarchal, yet the stagnation of fictional stories greatly stems from authors' assumptions that there is only The One.
Memo to the world: there is The Infinite. Deal with it, and start exploring it once already...
