It's clear that the mainstream (i.e. wh!te, European-settler-derived culture) of the United States has suffered an extreme collapse of the collective imagination. The effects of this collapse are written all over contemporary popular entertainments, which have grown progressively flatter and more formulaic and bombastic, and concentrated on a very few genres and conventions.
Christianity is perhaps not quite the cause of this, but beyond doubt this creeping devolution of U.S. entertainment and fiction has been strongly driven by reactionary Christian demands on popular culture. The Reagan administration of the 1980s, which pandered almost exclusively to "evangelical" Christians who adored the Reagan fascist counterrevolution as a restoration of "traditional" values, inflamed a tremendous amount of censorious sentiment in the United States, sustained by right-wing astroturf movements and buckets of cash trickling down from big donors to right-wing pressure groups and "research institutions".
Despite some high-profile public embarrassments these groups have never stopped applying pressure, and their demands for censorship have become increasingly normalized. They've successfully contributed to a general public sentiment that there's somehow too much sex and "degeneracy" in U.S. culture, even though popular entertainment has actually become extremely bloodless and desexualized. They've also been hastening the simplification of storytelling. These right-wing Christian audiences have an extremely particular taste in entertainment; they want everything stripped down to more or less the same Good vs. Evil narrative, like an Ayn Rand novel in which there's Good™ and Bad™ characters, heroes and villains who are completely static, bound to win and lose respectively.
This hasn't just been bad for entertainment; it's been bad for media criticism and the ability of Americans to interact with fiction. As pop culture has gotten more formalized and simplified into a kind of civic monomyth of heroism vs. villainy, it's been progressively easier for nerd culture to assume that ALL entertainment, ALL fiction, is reducible to formulae. Everything they consume is formulaic, and increasingly they're incapable even of processing more complex storytelling. They simply assume it's wrong in some way, "objectively bad" (i.e. not fitting a formula) or manipulative and cynical. It's as though everyone in mainstream pop fandom has accepted the premise that all storytelling is allegorical, always corresponding one-to-one with an enumeration of acceptable fictional tropes, the purported "correct meaning" of the story.
And perhaps as an inevitable consequence of this collapse, hastened by cynical propaganda rhetoric about "narratives" from such persons as Matt Taibbi and Glenn Greenwald and other corrupted journalists (these persons and many others function as freelance GOP operatives, more or less, while masquerading as "independent" or "heterodox" journalists), this bizarre notion that all stories are allegories has infected the interpretation of the news. It's widely appreciated that mainstream news reporting has a fictionalized aspect. There's a kind of sliding scale between the poles of maximally truthful journalism (which would really be a sort of history I think, for "history" is ongoing and comes up to the present) through various degrees of "human-interest" and opinion writing all the way to pure propaganda and mythmaking. Taibbi and Greenwald and other right-wing figures assert that ALL "mainstream media" (they doublethinkfully exclude themselves) is mythology and allegorical, with every event corresponding to a hidden "correct meaning". Extremist Christianity has again played a strong role here, for allegorical interpretation of the news in terms of apocalyptic Christian mythology has been a popular pastime for decades (e.g. The Late Great Planet Earth) and they've fed into the same antic ultra-right-wing culture that also spawns more secular forms of apocalyptic conspiracy theorizing about "the media".
And that's all the narrative I can must at the moment. Your humble narrator,
