I got as far as your claim that the KJV translation of Psa 12:6-7 proves that the Bible was preserved perfectly. You're a full-on kook.

By the way, here's Psalm 12:6-7 in the Dead Sea Scrolls:

"The LORD’s promises are pure pro]mises, like silver refined [in a fur]nace on the ground, purif[ied seven times. You, O LORD, will protect them; you will preserve] us from this generation [forev]er."

A totally different text from the KJV.
