why me wrote:But [Emma] did not understand polygamy and thus section 132.
This is one of the most ironic statements you have ever uttered Why Me.
So, Emma Smith, the wife of serial philanderer Joseph Smith, who had to stand there against her will and watch as he took the Lawrence sisters as additional wives, who had to find out about many of Joseph's other secret, fake "wives" through the grapevine, and who had caught him in the act with Fanny Alger back in the early 1830s, prior to any nonsense about "sealing power" and all the rest, did not understand polygamy, and you do?
Why Me, if there was ever, ever even one single, solitary individual in the entire history of the LDS Church who truly understood polygamy, it was Emma. Do not even go there. If you don't understand what I just wrote, then read it again, and think about it until you do.
Here is an interesting idea for you. Let's consider both possibilities here, ie: that Emma was in on the fraud, and that she was a true believer.
1) Emma in on the fraud.
Ok, so Emma was in on the fraud, and she fought Joseph tooth and nail about polygamy. He comes up with a "revelation" from God which justifies polygamy. She knows it's bogus, but she also knows that others of his followers know about this revelation. What are her options? She can fess up to the fraud, repudiate Joseph, and lose everything that his position has gotten her, her comfortable home (the Nauvoo Mansion House by this time), her status, her friends (they were TBMs, and undoubtedly would not take kindly to her "apostasy"), probably even her children, and be left out in the cold with nothing. Or, she can bite her tongue and go along with it, as she has done so far so many times.
2) Emma was a true believer.
Ok, so Emma was a true believer. She may not have liked polygamy, but hey, God told her that Joseph had to do it, so who is she to argue against God? So, just grit your teeth and bear it. And then, after Joseph dies, she refuses to go out West with the man acclaimed by a majority of remaining Mormons as Joseph's successor, and spends the rest of her life teaching her children that Joseph never practiced polygamy, that it was all Brigham's fault, etc. Hmm, some true believer, eh?
But regardless, whether she was in on the fraud, or whether she actually believed Joseph, there were very strong incentives for her not to repudiate Joseph and the "revelation" where the Creator of the Universe gives him permission to f*ck any woman he wanted.
