The author shows two uses of language manipulation: positive — in relation to the phenomenon of political correctness, the implementation of which he also considers a kind of manipulation, and negative — manifested in hate speech. Political correctness generally eliminates to some extent aggressive language — hate speech. Its influence can be seen in various spheres of social life (attitude towards other nationalities, sexual preferences, religion — non-denominationalism, etc.). The area where hate speech is spreading is widely understood politics. The conclusion is that while in many spheres of social life diplomacy is in force or is beginning to apply, politics is in a state of an ever worsening war.
