Article makes reference to a "fundamentalist Mormon" when talking about polygamy.
There is no such thing as a "fundamentalist" Mormon. Mormon is a common name for a member of The Church of Jesus Christ of Latter-day Saints. The Church discontinued polygamy more than a century ago. No members of the Church today can enter into polygamy without being excommunicated. Polygamist groups in Utah, other parts of the American West and elsewhere have nothing whatsoever to do with The Church of Jesus Christ of Latter-day Saints.
