In recent years, there seems to have been an increasingly dogmatic, virulent attack on academia under the pretense of "keeping politics out of academia." This pretense, of course, isn't based on a solid, objective criterion for what qualifies as "politics": from the theory of evolution and psychological analysis of gender dysphoria to climate science and renewable energy, demagogues and ideologues have found various ways to attempt to undermine the credibility of scientific and academic fields they deem undesirable for one reason or another.
Essentially, any scholarly research and scientific facts deemed inconvenient by demagogues and pseudo-intellectuals could easily be dismissed--and face opposition from followers of said demagogues and pseudo-intellectuals--under the guise of promoting freethought and accuracy, or under the banner of any number of bombastic but hollow claims. And because much of the public is misinformed or uninformed about exactly how academia works, it is relatively easy to propagate hyperbole and inaccuracies about how it functions compared to fields that are more familiar to most laypeople.
It seems to me that these attacks on academic research and researchers largely amount to shooting the messenger. When someone claims that a course on evolution has a "liberal bias," for example, the underlying idea is usually that to eliminate this "bias," the course must not teach evolution as a scientific fact--thereby ignoring long-established facts and findings of biology. It is a "damned if you do, damned if you don't" scenario for academics, then: either forgo intellectual and scientific integrity or keep facing accusations of "bias," "politicizing academia," "campus politics," etc.
So, essentially, it is not scholars that the demagogues and their followers have a problem with but rather the findings thereof and the facts revealed and studied by scholars. The scholars are merely the messengers of facts and knowledge that are inconvenient and politically problematic for certain people, and what better way to propose an alternative version of facts than to attempt to poison the well and undermine the credibility of those who spend their whole lives studying and expanding their and others' knowledge of facts?
"Shoot the messenger to undermine the inconvenient message--whether or not it is accurate and honest." That seems to be the motto of some public figures and their followers nowadays, and academia is one of the primary targets of this simple yet pernicious motto.
