Danger and harm can be intentionally programmed into any published content. The reason is social: the word is always action and invites action, but when it is written and deliberately speculates with the reader's consciousness, it is about neuro-linguistic negative effect on practical behavior and hence complicity in crimes influenced by reading. According to the author, markers for a "Dangerous Book" are: propaganda of ideology, immorality, illegality and obscene associations. But warns that in the sense of "the book as a product and an object" there are no Dangerous Books; Dangerous Books can be spoken of only in the sense of "the book as a media" and these are the texts spreading ethnic and religious enmity and hatred; the texts-accomplices in acts of ethnic cleansing, in crimes against the person and her rights.
