Believers who perpetuate the prophet Joseph Smith’s polygamy teaching are commonly called “Mormon fundamentalists” in the media, which is, presumably, one reason President Russell Nelson wants to shed the familiar “Mormon” name for The Church of Jesus Christ of Latter-day Saints, which forbids polygamy.

Meanwhile, debate persists over the frequent term “Muslim fundamentalists” for politicized or violent groups more precisely called “Islamists” or hyper-traditionalist “Salafis.”

The Religion Guy is now wondering whether the F-word has become so problematic that the news media should drop it altogether.

I say that because of a July 21 New York Times book review of Amber Scorah’s book “Leaving the Witness,” about her experiences within, and eventual defection from, Jehovah’s Witnesses.

(The Guy has not seen Scorah’s opus, but it’s hard to imagine it outclasses the superb pioneering Witnesses memoir “Visions of Glory” by the late Barbara Grizzuti Harrison, which goes unmentioned in the Times. While Scorah has left God behind, dropout Harrison turned Catholic.)

Reviewer C. E. Morgan, who teaches creative writing in Harvard Divinity School’s ministry program, repeatedly calls the Witnesses “fundamentalists,” which — historically speaking — is a religious category mistake of the first order.

Thus the question arises: If teachers at Ivy League theology schools, and copy editors at the nation’s most influential newspaper, don’t know what “fundamentalism” is (even as defined in the Associated Press Stylebook), maybe it’s time for the media to banish the word.
