In his defense, he didn't say he wanted multiple wives. He's not really that type to even talk about or comment on other women. He's very respectful and admiring of his wife. I felt his conversation(s) on this topic were doctrinal, not personal.
Interesting take on faith though. Black and white isn't faith. I gotta admit, it seems to take more faith to know all the dirty stuff in our history and still maintain some level of faith in the whole thing as possibly true. His approach is to reject what seems to be true about our history, rather than embrace it and deal with it.
But again, at this point, I was sorry I had opened up the rabbit hole. He's very happy where he stands in his relationship to the gospel. I hate to be one to disturb this in other people. If the goal of our life is to have joy and happiness, then stirring up doubt that shatters it all, in my view, isn't a goal of mine. We could argue whether it's better to be in bliss in the midst of untrue beliefs, or to be miserable with the truth in hand.
