That was great, and very helpful--particularly Dr. Peterson's point about the crows, and Ben's point about "unfalsifiable"--which to me illustrate the difference between what is theoretically falsifiable vs what in practice is falsifiable. While it theoretically posible to survey all crows that lived in Isreal back in the day, it is not possible in practice because we can't go back in time, and even if we could, it would not be practical to survey all crows then. So, in terms of practice, the very nature of the Book of Mormon renders much, though not all, of it unfalsifiable (not to be confused with LDS apologists rendering it unfalsifiable).
The problem is that the “nature” of the Book of Mormon does not render it unfalsifiable at all. There is plenty of background information given, notably about the power and complexity of the polities therein (lamanite and nephite). These polities are fairly complex with layers of bureaucracy and political control over other complex polities. While we don’t know everything about ancient Mesoamerica, we do know what kind of polities existed during the specified time period. The type of polity described in the Book of Mormon would have been one of the most powerful polities of the period.
I provided many details and references to back up this assertion on this particular page of my website:

This means that this polity would not be so minimal as to be undetectable. The only way apologists make it so is by reinterpreting the Book of Mormon in ways that strain the imagination.
An additional problem is that in ancient Mesoamerica, as in most cultures, the most powerful polities strongly influenced the behavior of other polities. The idea that this powerful Book of Mormon polity is not only undetectable, but had zero influence on the rest of Mesoamerica is, literally, unbelievable. I go into extensive details here:

Ben is schooled enough to realize that rendering the Book of Mormon unfalsifiable is “not a good thing”. As I already said, and provided a popper quote to demonstrate, if a theory that is actually falsifiable – as the Book of Mormon is – is manipulated by its defenders to make it unfalsifiable, that is a sign that the theory already failed. That is why Ben vigorously fought my accusation. He did not approve of Dan’s “White Crow” theory. I wonder how carefully you read the thread that you seem to have missed that.
