"Puritanism. The haunting fear that someone, somewhere, may be happy."
Most recently in reference to nuclear war vs. a non-Nato Ukraine.
"How can you be happy when there exists racism, sexism, white supremacy...
"We must punish you"
Don't you get it? If anything isn't perfect yet, it must be your fault. The problem is the Puritan himself isn't happy, and obviously happiness is natural and happens by itself. You must be punished, and then enslaved to work towards perfection, so we can finally reach Utopia.
Clearly, Utopia is the default. E.g. State of Nature. If we are not currently in Utopia, it must be due to the evil opposition of wreckers and heretics. Are you not fully on board? Only 99.8%, not 100%? Well it must be on you, because if you stopped opposing Utopia, it would plain simply occur.
Perfectly rational, see?
Extremely childish rationality, but rational given their extreme disabilities. Fundamentalism is cope for small minds who should never have been let out of the house.
