I believe the scriptures were "innerant", as you say, when God spoke. I just don't believe they remained so after having been passed through the hands of men for thousands of years and translated numerous times.
Besides show me in the Bible where it says they are "innerant". I believe the sciptures are the Word of God. God is perfect. The scribes who translated the bible over thousands of years were not.
As another aside, those who belive in "inerrancy" do not even agree on what it means. Once again you holding Mormons to a litmus test on Christianity that even "orthodox" Christians do not agree on.

There are over 5,600 Greek manuscripts containing all or part of the New Testament. Most of these manuscripts date to the Middle Ages. The first complete copy of the New Testament, the Codex Sinaiticus, dates to the 4th century. The earliest fragment of a New Testament book is the Rylands Library Papyrus P52 which dates to the mid 2nd century and is the size of a business card. Very early manuscripts are rare.
No two manuscripts are identical, except in the smallest fragments[9] and the many manuscripts which preserve New Testament texts differ among themselves in many respects, with some estimates of 200,000 to 300,000 differences among the various manuscripts[10]. According to Ehrman,
Most changes are careless errors that are easily recognized and corrected. Christian scribes often made mistakes simply because they were tired or inattentive or, sometimes, inept. Indeed, the single most common mistake in our manuscripts involves "orthography", significant for little more than showing that scribes in antiquity could spell no better than most of us can today. In addition, we have numerous manuscripts in which scribes have left out entire words, verses, or even pages of a book, presumably by accident. Sometimes scribes rearranged the words on the page, for example, by leaving out a word and then reinserting it later in the sentence.
Many inerrantists believe that the authorial recensions of New Testament texts are not only accessible, but accurately represented by modern translation.[citation needed] Though some inerrantists often prefer the traditional texts used in their churches to modern attempts of reconstruction, arguing that the Holy Spirit is just as active in the preservation of the scriptures as he was in their creation. These inerrantists are found particularly in non-Protestant churches, but also a few Protestant groups hold such views.
A young monk is assigned the prestigious task of joining the older monks in the copy room copying books of scripture. After being there for only a week, he goes to the head of his order and ask him how often they check against the older manuscripts for accuracy. The Head responded that to his knowledge it had never been done. The Head then suggests that the young monk take his keys, go down in to the crypts under the monastery and check the current copies against the older preserved copies. The young monk goes happily off to his new task. A couple of days later, he does not come to supper. The head goes down into the crypt to look for him and finds the young monk repeatedly bashing his head into the wall while crying in frustration. The head asks him “What’s wrong? Did me miss something?” The young monk says, an “R”. The head says “It’s just one letter, how bad can it be?” The young monk replies the word was supposed to be “celebrate”…
I love that joke, and IMHO it illustrates the point rather nicely.
