According to Pew, there are now more Evangelical Protestants in the United States than Mainline Protestants. Thankfully, the JWs hardly register in the grand scheme of things, below.
Some say we are witnessing the death of "intellectual Protestantism".
Let’s face it: so far as the great mass of American Protestants are concerned, theology is a dead letter. They are either “tribal Protestants,” going to church because their parents did, or because their neighbors do, or else they are Left Behind fundamentalists of the Huckabee persuasion, fundamentally anti-intellectual and indifferent to theology, or to any kind of intellectual inquiry. (Please note: There are no mentions of glossolalia or snake-handling in this blog.) Intellectual Protestantism probably survives in a few seminaries somewhere, but nobody cares. If I say “intellectual theologian,” to you, you will probably assume I am referring to some RC. Even then, the guy has probably, with very few exceptions, been dead at least 500 years.
