Here.  Dreger is an historian of science, who has herself been the victim of the thought police because she has discussed, sympathetically, disfavored views about transgender people.  Her main theme is that threats to academic freedom in universities come from three sources:   the "left" (as she calls the "identity politics left," which, of course, isn't the left, since for the actual left, only one identity counts, the human), the right (I.e., reactionary state legislatures that want to censor research and teaching), and corporate sponsorship (which wants universities to adhere to the "brand").
