“it’s obvious, Texan Tory, that you’re either 100% ignorant or are just intentionally ignoring two facts”
Ouch. Well, I’m not 100% ignorant, so that leaves us with that other thing you said about ignoring facts. I don’t think that all of the writings of Bruce R. McConkie are accepted as official church doctrine, even though he was an apostle. I will concede that your other point is correct, so that if a Mormon man marries, is widowed, then marries again, he will be considered to be married to both of these women once he dies and enters into the afterlife.
Regardless of Mormon doctrine regarding marital arrangements in the afterlife, Mormons, in terms of actual real-world religious practices, have been devout practitioners of traditional, monogamous marriage since their involvement with polygamy ended about 120 years, and they have fairly good statistics (lower divorce than average) demonstrating their committment to traditional marriage.
Yes and no.
On the one hand, you are right -- there's not necessarily a direct 1:1 correlation of McConkie's book to what is deemed "officially accepted LDS doctrine."
But that understanding basically falls on account of several points:
(1) BYU prof Stephen Robinson, in his co-authored book, HOW WIDE THE DIVIDE, states that LDS consider apostles and prophets to be essentially interchangeable. (That shows how much respectful authority is assigned to LDS apostles -- and nobody has ever specifically called out McConkie "on the carpet" for that 1966 published book...it was done for an earlier version)
(2) It was because of McConkie's earlier version that the LDS "First Presidency" realized in the mid-60s that McConkie's rewrite of Mormon Doctrine needed direct oversight. So, according to McConkie's son, LDS prophet Harold B. Lee assigned another member of the "First Presidency" -- later-to-be-named a "prophet" -- Spencer W. Kimball, to directly oversee the revised book.
That's what happened. Therefore, (3) there's absolutely no way the church would allow a book named "Mormon Doctrine" that's been in print all these years to continue to stand if it didn't represent mainstream Mormon doctrine.

Well, your year numbers are off. LDS, in most cases, didn't dissolve existing polygamous families in the early 1890s. Secondly, they continued on a behind-the-scenes basis to privately sanction over 200 additional polygamous unions between 1890-1910. They started cracking down on a few polygamous unions "for show" in the early 1900s...but real reform didn't set in until Grant was the president in the 1930s. (That's why the fundamentalist Mormons didn't break away until then).
...they have fairly good statistics (lower divorce than average) demonstrating their committment to traditional marriage.
Yes, but surprisingly Utah has a high singles rate among adults...showing that even this high commitment to marriage is starting to undergo cultural change.
