Interesting. I tend to avoid Mormon-themed material because it either seems to be created by outsiders whose narrative never really seems to fit with the facts I am privy to, or it's written by insiders who are so enmeshed that they cannot see how narrow their vision is.
It is very rigid and very full-on. I find that people who need or like that sort of rigid structure to their lives thrive and do very well within the church, but people who are a bit more, erm, independant feel stifled. It wasn't hard for me to leave. I left as soon as I was old enough that my parents couldn't force me to go anymore (in part because technically the doctrine requires a woman be married to enter Heaven and to me that always seemed wrong). The worst part about it being so full-on is that there is no such thing as a casual Mormon: you are either all-in or you are anti-Mormon. I spent the better part of a decade being defined by what I am not - and have finally reached a point that I can just be what I am - that when I read "mormon" material it's very uncomfortable for me. For instance, aside from being complete shit, the Twilight series author is Mormon so the books read very "Mormon" to an ex-mormon and I don't like it.
My dad was a missionary in Japan over 30 years ago. He still speaks fluent Japanese and travels there a lot for business.
I'm torn on polygamy. On its face I have no problem with polygamy (vs just polygyny or polyandry) although I wouldn't choose a polygamous relationship for myself. The women I know in polygamous marriages are all very happy and live in mordern cities and have jobs and use facebook and seem to have genuinely chosen their lives.
I have a hard time with the current fad for it in the media because I think it is portrayed as being significantly more sexy/dramatic than it actually is/was.
There's a lot of good info about mormons and feminists and polygamy here
