Irony poisoning

Irony poisoning is the process or altered state wherein one genuinely echoes provocative sentiments they once held ironically. Appearing in The New York Times in 2018, the term is often used to describe the normalization of extremist views through the use of humor, particularly in online spaces.

Notable examples
The New York Times used the term to describe the chain of events that led up to the attempt of German man Dirk Denkhaus to set fire to a house sheltering refugees after exchanging racist memes and Nazi greetings online. In 2022, the Canadian Anti-Hate Network accused Diagolon of using irony poisoning to desensitize users to hateful rhetoric through the use of online jokes and memes.
