Just let me say that I don't think there's one history book in print that's historically "true". There's always a point of view in conclusions about historical events with a certain bias. Why should I expect an absolute truth from a religious book, supposedly written by more or less faithful adherents of a church/religion? The whole idea doesn't make much sense to me. I guess we all know that the text of the first dictated manuscript of the BoM has been changed numerous times, and if we consider how this "ancient record" has supposedly been "translated" into English, there's no way to say it's been changed because of mistakes made by Joseph or his scribes (if we accept such a divine being that produced the English text). I wouldn't expect anyone to join the LDS Church just because he/she likes the teachings of the BoM. IMO, the Church of the Nephites was quite a different thing than what we now have in Utah with its "Book of Abraham", "D&C", its different temple culture etc.
