You conflate Calvinism and Puritanism with what happened over 300 years ago in Massachusetts Bay Colony.
Your theory and claims are weak.
Puritanism degenerated into Unitarianism. The self righteous sanctimoniusness remained even as the belief in revealed religion evaporated. Puritanism is just another word for Calvinism with its belief in predestination and rule by the clerical elite. This attitude of perpetual virtue never went away. Today’s leftist believe just as strongly as the Mathers that only their beliefs should be allowed and all others represent evil. The deracinated Puritans absorbed the sanctimony of political marxism and spread it through both universities and churches in the 20th century. The woke people have absorbed this poison and carry on the tradition of sanctimony, self righteousness and belief in a now secular illuminated elite, Calvinism is one of the worst concepts ever launched. the world would be much off had Calvin never lived.
