Modern world challenges the man in some new global ways. Thus, the people's need in ideologies showing the ways of living is still strong. The left-wing discourse -the ideas of social justice, equality, the elimination of class division and restrictions on private property -is one of the most popular ideological layers today. Many researchers turn their attention to the modern left-wing agenda, but most often approach it from economic, political, sociological or historical positions. Within the framework of this study, based on the works of various scientific fields, a generalizing axiological, semiotic and structural and functional assessment of the left-wing ideological spectrum in its semantic contents, mythological and religious manifestations, media and artistic forms and socio-cultural influence is carried out. The result of the research was the formation of a general picture of the phenomenon of left-wing ideological discourse, which in the mechanisms and principles of its existence is comparable to mythology and religious trends, and in propaganda methods and approaches is based on emotionality, aggressiveness, a "black-and-white" vision of the world and ineradicable conflict. At the same time, the collectivist, humanistic motives of left-wing ideologies, their practical orientation (although also controversial) and the use of a scientific and philosophical base are also emphasized.
