For me, the difficulty with the situation is that so little is taught about the true events, so when I became aware of them, it really threw me for a loop. I was able to reconcile it all now, but especially when I was such a student of the gospel for so many years, it is unfortunate the church hasn't found a way to teach the history more openly.
Polygamy hasn't been a major thing for me (since I'm not required to live it), it is not a deal breaker and I can live with the fact that it was commanded for a while, then not commanded any longer. I'm ok with that. But I will admit, it makes me a little less certain of church leaders who make statements like they do in the Prop 8 campaign, because I can see how in the past, despite what was said, things can change.
I think we are in a new age now with the Internet that a lot more people really know the facts than before when the church didn't like talking about negative things, so didn't try to lie about it, but certainly didn't choose to address it. My 14 year old daughter asked me about it the other day, because she heard about it and was worried that in heaven she will have to share her husband. I know for me, I certainly wasn't thinking of polygamy at 14, or at 24, for that matter. The youth today are exposed to a lot more of these interesting topics in the church.
Luke: "Why didn't you tell me? You told me Vader betrayed and murdered my father."
Obi-Wan: "Your father... was seduced by the dark side of the Force. He ceased to be Anakin Skywalker and became Darth Vader. When that happened, the good man who was your father was destroyed. So what I told you was true... from a certain point of view."
Luke: "A certain point of view?"
Obi-Wan: "Luke, you're going to find that many of the truths we cling to...depend greatly on our point of view."
