Its like a line of dominoes. One falls, the rest fall. I began to come to the conclusion that most of the proofs supporting KJV-onlyism really were not sound.

For example, Psalms 12:6,7 only suggests that God will preserve His Word. They do not identify how or what. To use those as a proof text for KJV-onlyism is to do what Dr. Tabb did. Read more into the verse than what is there.
