The final comments also support the theme: Some of the more conservative authors presently complaining are doing so, Dulaney thinks, because they fear the growing presence of a more diverse community and a wider acceptance of the same. Trends which will continue to grow into the future.

I think this might be attributing too much malice to the author in question though; Larry C seems more like a somewhat thoughtless writer annoyed that his low-brow entertainment books are not considered to have the same merit as Dulaney's stuff, backed up by an echo chamber online community.
