Pew did a new study of why people choose a new place to worship. They included non-Christians, but in all the graphs they are lumped together as “non-Christians”–Jews, Muslims, Buddhists, Hindus, Sikhs, etc. It is assumed that “houses of worship” have “clergy.”
Emma Green at the Atlantic writes about it in “It’s Hard to Go to Church.” Here, non-Christians are completely omitted. It’s all about “going to church.” And she assumes religious activity normally happens on Sunday.
Wake up, Pew! Wake up, Emma! American Religion is a lot more diverse than that.
