While i am by no means a KJVO, I will have to disagree with your view that the KJV is not the perfect Word of God. I find it rather hard to see any modern translations from the Westcott and Hort family being anything but corrupt with their dealing of the Word of God, II Corinthians 2:17. You stated that no one believed in the KJVO position before Wilkinson which I believe to be true. But at least two men believed in the superiority of the Textus Receptus to the Westcott-Hort Revised Text. John Burgon who wrote a great defense for Mark16:9-20 and Herman Huskier. This in the early days of the Revised Version.
If you wish you can call me a TRO. But while I could never advise anyone to read from Nestle-Åland Texts, if one prefers strongly to read an NIV or NAS I wouldn’t argue with them.
One things I do agree with KJVO on, is God did preserve His Word for all. And while many KJVO will disagree with me here but I see the Geneva Bible, NKJV, Jubilee Bible just to mention a few to also be the complete perfect Word as they have TR connection.
I admire greatly KJVO because they dare to take God at His Word in that He would preserve it for us, Psalms 12:6-7; Matthew 24:35. When I see comments like those modern translations make about passages like Mark 16:9-20; and John 7:53-8:11; I John 5:7 it makes think of this statement of the devil; “Yea, hath God said.” Genesis 3:1. Not to mention with John 7:53-8:11 pretty sure it was fulfilling Jeremiah 17:13.
At very least the KJVO can rest in the fact that they drink, because of their desire the sincere milk of the Word, I Peter 2:2.
