There has been no dispute over the organization of the section until you arrived. Please take a look at our primary source for the section's data: the Pew Forum's Religious Landscape Survey. Please note, the data on those professing a faith—any faith—precedes the data on those who are "unaffiliated" ("atheist", "agnostic", "nothing in particular"). OK? Do you understand now? The section's current structure does reflect the professional standard.—
