One of my counterparts who has been in ministry for many years and whose ministry is large and popular is a KJV-only guy (and an Arminian, and a Dispensationalist), "Independent Fundamentalist Baptist (IFB)." IFB is not a denomination, but a description of a church and ministry like his.

We get along outside of church, but if I was preaching, he would have to interrupt and call out my "Calvinist" error and condemn my use of the NASB and ESV as "Satanic."

IFB is almost cultlike in their adherence to fables and myths, twisting of Scripture, and alienating all other Christian ministries as misleading at best, Satanic at worst.
