Actually, the NYT article is titled, “Mormons Offer Cautionary Lesson on Sunny Outlook vs. Literary Greatness”.
Here, we are told we are both too sunny, and optimistic, and that in combination with our reticence for explicit sex scenes, is what has keep us back from greatness. They also point out, quite pointedly, that we tend towards genre fiction instead of literary fiction, and various excuses are given for that.
In all fairness, we are not yet fulfilling Orson F. Whitney’s prophecy, but they did leave out many prominent LDS authors such as Richard Paul Evans, Ally Condie, Brandon Mull, Brandon Sanderson, and Eric James Stone.
I think they mistake our faith and hope for naive optimism and lack of philosophical depth. But it is telling, we have not sought prominence in the same vaunted halls as the elite would. Should we feel bad we have not measured up in literary fiction? Or should we take up our swords and phasors and give those literati a run for their (literary) lives? I mean that literarily.
