The fundamental thesis is
> Three generations ago, literature professors exchanged a rigorously defined sphere of expertise, to which they could speak with authority, for a much wider field to which they could speak with virtually no power at all.
Hence all the references to various scholars and their works.
Nowhere does the author bash Trump or say his voters are uneducated imbeciles. The quote most related to this is
> For going on 50 years, professors in the humanities have striven to play a political role in the American project. Almost without exception, this has involved attacking the establishment. As harmful as institutionalized power can be, as imperfect as even the most just foundations inevitably appear, they are, as it turns out, all we’ve got. Never has a citizen been so grateful for institutions — for functioning courts, for a professionalized FBI, for a factually painstaking CBO or GAO — as since November 2016.
Which boils down to "The humanities anti-establishment position needs to be toned down. This election when many of us did not get an outcome we wanted, we realized the value in having strong and trustworthy public institutions."
The main theme of the essay is self-awareness:
> Yet the editorial logic of right-wing media resembles closely the default position of many recent books and dissertations in literary studies: The true story is always the oppositional story, the cry from outside. The righteous are those who sift the shadows of the monolith to undermine it in defense of some notion of freedom.
Considering the essay starts out with
> Can the average humanities professor be blamed if she rises in the morning, checks the headlines, shivers, looks in the mirror, and beholds a countenance of righteous and powerless innocence?
The takeaway is that humanities professors have become ineffective because they've traded expertise for politically motivated analysis. There's a feel good, all inclusive, woo woo diversity culture about the humanities, but its come at the price of critical analysis and discerning judgment. Instead of providing a a critical, reasoned opposing view, they've become increasingly radical and reactionary. Instead of seeing their view as a small, but important contribution to the greater project of society building, they've tried to monopolize the project. The end of the essay reaffirms that the humanities have something to offer, but that that offering has to be a balanced towards improving the establishment instead of encouraging critiques with no means of improving or fixing it.
