Which methods do authorities not use to suppress people fighting for freedom?

According to the passage, the religious opponents of freedom used 'Inquisition, by excommunication, tortures and banishments, and the total denial of man's search for freedom.' All four — Inquisition, excommunication, tortures, and banishments — are explicitly mentioned as methods to suppress those fighting for freedom. Persuasion is NOT mentioned in the passage as a method used by authorities. Therefore, the method authorities do NOT use (per the passage) is Persuasion.
