Because the pro-DNA argument is closely tied to a specific geographical model, I'd like to reiterate that there is no official geography for Book of Mormon events. Eventually, I'll discuss the various geography hypotheses and will offer the reasons why I believe that the Mesoamerican model fits best.
But for now it's important to understand that believing Latter-day Saints can respectfully disagree as to where the events described in the Book of Mormon took place.
Elder Dallin H. Oaks, speaking of those who participate in non-official venues wherein church-related topics are discussed, observed that sometimes "a volunteer will step forward to present what he or she considers to be the church's position. Sometimes these volunteers are well-informed and capable, and they contribute to a balanced presentation. Sometimes they are not, and their contribution makes matters worse. When attacked by error, truth is better served by silence than by a bad argument."
