The American system has too many checks & balances for the dystopian vision of this author, but at the same time, the rise of a certain kind of right-wing nationalism is happening in many places, and the nefarious "alt-right" is on the move.  Richard Spencer is planning speeches at Texas A&M and Michigan, and posters promoting white supremacy have started appearing on campuses in unprecedented numbers.  Some are by American Vanguard, "The New Face of Patriotism."  They want an all-white, Muslim-free America.
So while the article certainly is hyperbolic, there is a festering pot of goons out there suddenly feeling like it's their time to move.  In that sense, yes, it's time for decent people to watch out for one another.
