The video may be fake, but what they are saying is what is actually practiced in islamic societies under sharia law and the majority of muslims living in the West favors sharia law above constitutional law.
If any thing it is Constitutional democracy , pluralism and the rule of law more than anything else that enabled Western societies to be prosperous and "happiest in the world". Without it so called Christian values are anything one bunch of Christians declare they are over another bunch of Christians. Should the nation’s laws be based on Christian religious text or those Christian values (whatever they may be), it would be no better than Islamic theocracy. There are plenty who call for a Christian Sharia Law in America too. "Sharia law may be coming to America. But it's Christians who are bringing it." https://www.adn.com/opinions/nation...erica-but-its-christians-who-are-bringing-it/
Christian/Jewish values and virtues are the foundation of Western societies, not "pluralism", whether you like it or not. No point in further arguing with you since you obviously have a hate for Christians.
Then as this thread indicates, the Christian/Jewish values and virtues you refer to include a tribal hate for all things Muslim. This country was certainly not founded on those values.
