The sidebar biography of the author:
Max Perry Mueller is Associate Editor of Religion & Politics, a forthcoming weekly online journal, a project of the John C. Danforth Center on Religion & Politics at Washington University in St. Louis. He is currently the Eccles Foundation Mormon Studies Fellow at the Tanner Humanities Center at the University of Utah. He is a PhD candidate in the Study of Religion at Harvard University writing a dissertation on Mormon race relations.
Also the author self-consciously refers to himself within the article:
"As a scholar of Mormonism, and not (as I hope is obvious) as a spokesperson for the LDS Church, I must stay continuously alert to the unique context my work inhabits."
Yeah, I'd say the article is written by a Smith disciple.
