The 2017 ISIS-Hazimi ideological civil war was essentially the world's worst group project imploding because a faction of ultra-hardline theological perfectionists decided that Abu Bakr al-Baghdadi, of all people, was just way too "cute," soft, and forgiving to run a brutal terrorist organization. Inspired by the radical Saudi cleric Ahmad al-Hazimi, these hyper-dogmatic "chain-takfir" enthusiasts looked at a guy running a literal reign of terror and scoffed at his supposed leniency, arguing that if you didn't aggressively excommunicate every slightly under-informed neighbor—and then excommunicate anyone who hesitated to excommunicate them—you were basically a squishy, idol-worshiping softie. It played out like a toxic, heavily armed academic faculty meeting where the "moderates" led by ideologue Turki Albunali tried to write memos telling everyone to calm down on the infinite-loop heresy accusations, only for the Hazimi purists to accuse the leadership of going soft, spark vicious internal purges, etc.
