King James onlyism started as a reaction to changes made by textual critics based on different manuscripts than those used for the KJV. It all started with the Revised Version which was published in the late 19th century. It claimed to be a simple revision of the KJV; but it was later discovered that it used readings based on Textus Sinaiticus and Textus Vaticanus. This upset a lot of people, understandably so since it was all done by stealth. As time went on, and more translations were made based primarily on those two manuscripts, hysteria began to set in.
Wow, it's amazing. You actually admit that the Modern Bible Movement (by Westcott and Hort) is based on lies and deception.
That does not sound like something God would fully bless.
You said:
Instead of thinking and talking about it logically, conspiracy theories began to proliferate and eventually people started claiming that the only really true word of God was the KJV.
You are misinformed about the origins of those who believed the KJV to be the perfect Word of God.
We see this belief as early as the 1600s.
The General Baptists of England published the "Orthodox Creed."
In 1678. It says,
"And by the holy Scriptures we understand the canonical books of the Old and New Testament, AS THEY ARE NOW TRANSLATED INTO OUR ENGLISH MOTHER TONGUE, of which there hath NEVER been any doubt of their verity, and authority, in the protestant churches of Christ to this day."
They then list the books of the Old and New Testaments and then say,
"All which are given by the inspiration of God, to be the Rule of faith and life."
What Bible do you suppose these people were using in 1678? It was English and there can be little doubt that what they are talking about is the Authorized Version of 1611.
The year 1678 is 67 years after 1611.
Also, keep in mind that Richard Simon is often regarded as the "father of modern biblical criticism". He was a 17th-century French Catholic priest, and he did not influence anyone in England at that time.

1762 – Cambridge University, guided by Dr. F.S. Paris does an update with spelling changes to reflect the new modern English word spelling uniformity mandated by the widely accepted 1755 Johnson’s English Dictionary. A group of “1611 Loyalists” burns the Cambridge Warehouse down in protest, destroying all but several copies.
1769 – Oxford University, guided by Dr. Benjamin Blayney, takes a surviving copy of Cambridge’s 1762 revised and modernized KJV text, and adds some more updates,. A group of “1611 Loyalists” burns the Oxford Warehouse down in protest, destroying all but several copies.

Taken from the Association of Baptists 25th meeting 1830
“We the church of Jesus Christ being regularly baptised upon the profession of our faith in Christ are convinced the concessive of associate churches. WE BELIEVE THAT THE SCRIPTURES OF THE OLD AND THE NEW TESTAMENTS AS TRANSLATED BY THE AUTHORITY OF KING JAMES TO BE THE WORDS OF GOD AND IS THE ONLY TRUE RULE OF FAITH AND PRACTICE.“
1857:
"The general excellence of the English Version being admitted, ITS PERFECTION ASSUMED, AND THEREFORE ALL PRECEDING AND SUBSEQUENT VERSIONS MUST BE UNWORTHY OF NOTICE; nay, even the original text need not be consulted...” (Thomas Kingsmill Abbott, The English Bible, and Our Duty with Regard to It, 1857; 1871).
1882:
"I unhesitatingly say, that the same Holy Ghost who gave inspiration to the Apostles to write out the New Testament, presided over and inspired those men in the translation and bringing out of the entire Bible in the English language. And I also say, that no version since, brought out in the English language, has the Divine sanction...Now, why would God cause at this age and in these trying times, versions in the same language to be brought out, to conflict...?...He would not...I FURTHERMORE SAY, THAT THE KING JAMES' TRANSLATION OF THE BIBLE IS THE ONLY DIVINELY INSPIRED..." (William Washington Simkins, The English Version of the New Testament, Compared with King James' Translation, 1882).
1890: The Supreme Court said,
"the practice of reading THE KING JAMES VERSION OF THE BIBLE, COMMONLY AND ONLY RECEIVED AS INSPIRED AND TRUE by the Protestant religious sects." (Decision of the Supreme Court of the State of Wisconsin Relating to the Reading of the Bible in Public Schools, 1890).
1897:
“IN A CERTAIN SENSE, THE AUTHORIZED VERSION IS MORE INSPIRED THAN THE ORIGINAL...” (Minutes of the Annual Meeting, General Association of the Congregational Churches of Massachusetts, 1897.)
Mates Creek District Association of Old Regular Baptists by 1905, and perhaps earlier, had an Abstract of Principles that claimed that:
"the Scriptures of the Old Testament and New Testament, as translated under the reign of King James, are a revelation from God, inspired by the Holy Ghost."
