The usual procedure is to first lie about something the conservative (or libertarian) supposedly said to whip a "Twitter mob" into a hateful frenzy.  The local media then pick up on it and pile on.  Spineless faculty "colleagues" either cower in fear or join the mob by signing a petition to curry favor with the administration (to increase their chances of another 1 percent pay raise).  If the conservative or libertarian professor is not tenured, he or she is fired.  Otherwise, he or she is marginalized, harassed, discriminated against, and "encouraged" to leave voluntarily to avoid such a miserable existence.  No human resources bureaucrats are ever concerned about "hostile work environments" when it comes to academic conservatives or libertarians; only the Left is to be protected from hostility and "insensitive" speech.
