[The letter writers use] the same tenuous, abuse-prone, guilty-by-association tactics that the far right has used to tar academics by linking them to Communism or Islamism… [They are] trying to radically narrow the bounds of acceptable speech and inquiry… A closer look at the letter lays bare the specific ideological orthodoxies and political tests that at least hundreds of linguists now feel comfortable openly imposing on their colleagues… [They are] poring over years of individual tweets, asserting uncharitable interpretations of those they highlight, assigning guilt by association, and imposing multiple orthodoxies that are incompatible with academic freedom… The desire to significantly narrow the bounds of acceptable speech is not a fringe proposition; it is a project that hundreds of people in a single academic field are willing to pursue openly.
