Why is Protestantism also listed as an element of modern civilization?

Because Protestants must have written close to history! The concept of ideas has a great influence on the history, sociology, politics, nationalism and socialism of the 20th century. For example, some people regard it as a type of economic development influenced by secular ethics. Other theorists are concerned about the relative decline of capitalist economic influence in the United States and Britain. In the reformation of Protestants in 16 and 17 centuries, Protestants also wrote the corruption of Catholicism into this history. You know, the religious extremism of Protestants from Britain to North American colonies at that time was not much worse than that of terrorists today!
