“This church has nothing whatever to do with those practicing polygamy,” said LDS President Gordon B. Hinkley in 1998, “They are not members of this church.” The religion itself focuses on home life, but it feels skin deep. For example, Kody is always talking about how much he loves the institution of marriage, but he’s always ‘falling in love with new people.” Basically, he loves creating new family members but has trouble taking care of the family he already has.
