What is the opinion of the LDSers about everyone making a racket about archaeology and the Book of Mormon?
I would say that, for most of us, our belief in the Book of Mormon doesn't require physical evidence any more than my belief in the Bible does.
To begin with, I don't personally think there will ever be conclusive proof that the events described in the Book of Mormon took place. Most LDS archeologists today are of the opinion that a great many of the events described in the book probably took place somewhere in Central America, but their has never been any official statement to that effect. So, not only do they not know precisely where to look, they don't even know exactly what they're looking for. Obviously, there are a great many archeological sites being excavated at this time. We all know that there were people here in ancient times. But here's the question we must ask: How would anybody be able to identify a site as being Lamanite or Nephite specifically? How would archeologists know, based on the very minimal clues found in the Book of Mormon, that they'd found an ancient Nephite city? I'm pretty sure they're not going to stumble upon a road sign that says "Zarahemla: 5 km."
When people point out that the cities, landmarks, etc. in the Bible can be positively identified, they seem to forget that these places have been almost continuously populated for thousands of years. Had no one lived in Jerusalem or Jerico or Capernaum for the past 2000 years and their locations with respect to other cities never described in the Bible, I wonder how easy it would be to zero in on them? People also will occasionally mention certain plants or animals that they say did not exist in the Americas prior to the Spanish conquest but which are mentioned in the Book of Mormon. Ever student of the Bible is aware that lions were known in Israel in Biblical times, and yet
the very first two lion skeletons ever unearthed in that part of the world were found as recently as 1983. Prior to the 1960's, not even any artistic depictions of lions had been found. Did these people come to accept the Bible as true only after archeological evidence of lions came to light in 1983? After all, by their own logic, if there is no archeological evidence for something, obviously it's false. Furthermore, neither archeologists nor Egyptologists have found evidence to prove that the Exodus ever took place, even though billions of people today believe it did.
Speaking of something along the lines of archeological evidence, I'm just going to give you one very brief example of something that I personally found to be interesting.
The Book of Mormon, was translated by Joseph Smith, Jr., then a 23-year old boy with a third-grade education. His background was in farming. He lived in rural New York state in 1830 and had no knowledge of ancient cultures, either American or Middle-eastern. Joseph claimed that the record he translated was written on plates that had the appearance of gold. They were etched with strange characters which resembled Egyptian hieroglyphics and were bound together using metal rings, like a book. They had been stored in a large stone box and buried for centuries in a hillside near his home. When Joseph described these plates, he immediately became the laughing stock of upstate New York. Egyptian letters engraved on gold plates and hidden in a stone box! How couldnything be so ludicrous? No one had ever heard of such a thing, and so of course it was dismissed as not only far-fetched but as virtually impossible.
Now, jump forward almost 100 years. In 1933, the Plates of Darius I were discovered in a stone box in a palace in Persia. They dated from about the same time as the earliest Book of Mormon plates. Half of the plates were gold and half were silver. They were very similar in appearance to the plates Joseph Smith had described. Since then, a number of other ancient records have been discovered -- all of them written on metal plates, any many deposited in stone boxes. They are on display at museums throughout the world (Chicago, Tehran, Lima, Rome, and Paris). Don't make the mistake of assuming that their content is the same as the content of the plates Joseph Smith translated, because it wasn't. The content, of course, is beside the point. What is significant is that archealogists now know that it was common for ancient people in various parts of the world to record their histories and other important information in this way. Joseph Smith didn't know this, and yet, in spite of all the ridicule, he never changed his story. History has now vindicated his claims in this regard.
Finally, although archeological evidence for the Book of Mormon story on the American continent may be minimal, the book does start in Jerusalem and describes in some detail the journey by Lehi (the group's patriarch), his sons and their families from there to a location somewhere along the Arabian Peninsula. Not only did Joseph Smith have absolutely no background whatsoever about the Arabian Peninsula, neither did any but a handful of scholars. It is possibly today, to recreate that journey and to spot natural landmarks described in the Book of Mormon, included an extremely isolated oasis where they camped, at the exact locations they would be expected to be found. There is even an ancient burial ground with almost exactly the same name as the one given in the Book of Mormon. This burial ground is not mentioned anywhere in the Bible or in any sources Joseph would have had access to.
At any rate, with respect to the lack of archeological evidence to prove the Book of Mormon, and in answer to your question, it doesn't bother me in the slightest. For one thing, many of the plants, animals, etc. that were once thought not to have existed here in Book of Mormon times have now been identified. So the list of proof against the Book of Mormon is steadily dwindling. There is considerable linguistic and cultural evidence to support the premise that the Book of Mormon truly is what it purports to be. In my opinion, this evidence is more compelling than anything else. The existence of highly complex chiasms, distinctly Hebrew sentence structures and idioms, etc. and various wordprint analyses are clear evidence in my opinion that the book is an ancient record and not the product of a 19th century imagination. Perhaps I find those evidences more compelling simply because I have an interest in linguistics, etc. But again, I don't base my belief in the book on any of those things. They are just frosting on the cake, as far as I'm concerned.
