The LDS practiced polygamy until it was forbidden as a condition of statehood for Utah. A number of LDS sects still do practice it, and though they are officially not recognized by the official LDS leadership anymore, many members of the LDS are emotionally torn on the issue and look the other way. There are other polygamous groups in the US. There are even other religious polygamous groups--such as one nutcase group locally that believe that black people are the real Jews. There was a recent murder of a second wife here. This group was based VERY loosely on the polygamous LDS sects, however, because of the mention of salvation being attached to multiple marriage. This is a misrepresentation of early LDS beliefs but is distantly similar.The part to me that was the most amusing was the idea that some ultra-close-knit society would welcome outsiders with clearly VERY different cultural standards because they are also polygamists. Uh, yeah. Because all polygamists are the same, right?
