I think your position is not warranted. The items for example of a highly repetitive phrase, common in the Bible "and it came to pass" and King Jame English writing style are not easily confusable items. One can associate those with the Bible, which can aid in one's memory.
So you haven't made an argument which justifies that these items which are easily remembered due to high repetition and association with the Bible could possibly have been implanted by Hurlbut in all the witnesses or that the witnesses would have confused these items in the Book of Mormon with Spalding's MSCC.
It doesn’t matter what you think. I have never accused the witnesses of lying, and you are misrepresenting me when you say otherwise. I think your position amounts to mind reading and unwarranted speculation, but I wouldn’t try to misrepresent your position. I have always argued that false memory is a likely explanation in light of evidence that Joseph Smith did not use a MS in the production of the Book of Mormon. In the process of this discussion, my theory has gotten stronger, while yours requires ad hoc hypotheses and wild speculation.
The KJV English is a confusable item, especially for a minister who wrote many items. If it’s true that Spalding was called “Old came to pass,” it’s doubtful that that appellation resulted from one MS. Finally, you can’t say what is confusable and what isn’t based on such meager sources. You can’t tell what associations the witnesses made since they didn’t themselves say how or why they remembered such things after twenty years. I don’t think Hurbut is responsible for all the content in the witnesses’ statements, but he likely transmitted information from one witness to another. For example, he could have infected a witness by asking: so and so says they remember the MS was written in the Old English, do you remember that too? And they might say: “I have a vague memory of his reading to me in that style—it could have been the MS Found.” Loftus’s research would suggest that this could become a more certain memory over time. So when you read their statements, you are reading the end result and do not know the process by which the came to remember things after reading the Book of Mormon, or being told what was in the Book of Mormon.
