You and other KJV-only advocates have not demonstrated soundly from the Scriptures that Psalm 12:6 supports a modern, man-made KJV-only view.
You should follow your own advice and reconsider your inconsistent, unsound, non-scriptural KJV-only position.
I do not believe Psalm 12:6-7 explicitly teaches a KJVO Position. But the argument that the words "them" in vs 7 are not the words of the Lord are absurd. Of course that also depends on what you think is KJVO, depending on how you define it I may or may not be King James Only:
I borrow this next list from David Cloud:
"If “King James Only” defines one who believes modern textual criticism is heresy, call me “King James Only.”
if “King James Only” defines one who rejects the theory that the “preserved” Word of God was hidden away in the Pope’s library and in a weird Greek Orthodox monastery at the foot of Mt. Sinai (a monastery which has a room full of the skulls of dead monks) for hundreds of years, call me “King James Only.”
If “King James Only” defines one who believes that it is necessary to have one biblical standard in a language as important as English and who believes that the multiplicity of competing versions has created confusion and has weakened the authority of the Word of God, call me “King James Only.”
If “King James Only” defines one who believes that the KJV was
given by inspiration, I am
not“King James Only.” The authority of the King James Bible is the product of preservation, not inspiration. The term “inspiration” refers to the original giving of the Scripture through holy men of old (2 Tim. 3:16; 2 Pet. 1:20-21). At the same time, I agree with the
Pulpit Commentary when it says, “We must guard against such narrow, mechanical views of inspiration as would confine it to the Hebrew and Greek words in which it was written, so that one who reads a good translation would not have ‘the words of the Lord.’” To say that the King James Bible is the inspired Word of God in the English language because it is an accurate translation of the preserved Hebrew and Greek is not the same as saying that it was
given by inspiration.
If “King James Only” defines one who believes the English KJV is superior to the Hebrew and Greek texts upon which it was based, I am
not “King James Only.” In fact, I believe such an idea is pure nonsense, as it would mean the pure and preserved Word of God did not exist before 1611.
If “King James Only” defines one who believes that the King James Bible is advanced revelation over the Hebrew and Greek texts that God gave through inspiration to holy men of old, I am
not “King James Only.”
If “King James Only” defines one who believes that we do not need to study Greek and Hebrew today or that it is not important to use lexicons and dictionaries, I am
not “King James Only.” God’s people should learn Greek and Hebrew, if possible, and use (with caution and wisdom) study tools. When the Bible says that “holy men of God spake as they were moved by the Holy Ghost,” we know that the words they spake were Hebrew, Aramaic, and Greek words. But foundational to the study of the biblical languages is a thorough understanding of the textual issue. We must study the
right Greek and Hebrew, and we must also be careful of original language study tools, because many of them were produced from a rationalistic perspective and with great bias against the God-blessed Received Text.
If “King James Only” defines one who believes the preserved Word of God is available only perfectly in English, I am not “King James Only.” The Masoretic Hebrew Old Testament and Greek Received New Testament translated correctly into any language is the preserved Word of God in that language, whether it is German, Spanish, French, Korean, or Nepali.
If “King James Only” defines one who believes that translations in other languages should be based on English rather than (when possible) Greek and Hebrew, I am
not “King James Only.”
If “King James Only” defines one who believes that a person can only be saved through the King James Bible, I am
not “King James Only.” It is the gospel of Jesus Christ that is the power of God unto salvation (Rom. 1:16), and even a Bible that is textually corrupt contains the gospel.
If “King James Only” defines one who believes that the King James Bible’s antiquated language is holy or who believes the KJV could never again be updated, I am
not “King James Only.” I doubt the KJV will ever be replaced in this apostate age, but to say that it is wrong to update the language again after the fashion of the several updates it has undergone since 1611 is not reasonable. Having dealt extensively with people who speak English as a second or third language, I am very sympathetic to the very real antiquation problem in the King James Bible. At the same time, I am not going to trade an excellent Bible with a few problems due to old language for a Bible filled with error due to a corrupt text and/or a corrupt translation methodology (e.g., dynamic equivalency).
If “King James Only” defines one who believes that he has the authority to call those who disagree with him silly asses, morons, and jacklegs, and to treat them as if they were fools because they refuse to follow his (or her) peculiar views, or if it defines one who threatens to sue those who challenge him (or her), I am
not “King James Only.”
