To convince readers that censors have unfair motives, the author uses rhetoric to appeal primarily to emotion.
The author is using the manipulation of the receiver's feelings as a way of convincing him of the validity of his argument. The appeal to emotion can be done in very different ways, causing your recipient a good feeling, such as joy and excitement, or bad, like fear and guilt. In appeal to emotion, the validity of arguments is ignored, taking into account only those that seem pleasing to him, being considered an irrational way of playing something
This can be perceived when the author says that reading is a path to freedom, that nobody should prevent this path, however, this impediment is increasingly frequent in the country.
