@Krish55 Actually, you have a point. Some of the most secular among us engage in "celebrity worship."

I think you'll find that the term secular religion was initiated by Rousseau, intending it to represent a social belief system which excluded theism, and was perpetuated by Robespierre at the French Revolution. And for a staunchly catholic country in C18th, France has remained proudly secular since.
