There are splinter groups that want polygamy and they were called poligs or something. The muslims want several wives to I expect that polygamy will come back through Obama.
TRUE Mormons (Flds) actually FOLLOW what MORMON scripture tells them to do (D&C 132).
The LARGEST group of MORMONs is run by a junta of spineless weasels that threw their GOD under the bus in favor of statehood.
Their fate is shown by the words of the Great Living Prophet MORMONism ever had:
"Now if any of you will deny the plurality of wives, and continue to do so, I promise that you will be damned;
and I will go still further and say, take this revelation, or any other revelation that the Lord has given,
and deny it in your feelings, and I promise that you will be damned.
Brigham Young - JoD 3:266 (July 14, 1855)
There are also a group of Unitarian universalists that support polyamory as well. http://www.uupa.org/
