Although I won't call KJVO heretics, I believe you are missing the boat on what KJVO is. It's not what you are describing. Perhaps ask Luke2427 to elaborate on just what he means here. It's not simply calling another an heretic over their choice of text brother.

The problem is that Luke2427's take on KJVO simply isn't reality. I am KJVP (probably KJVO by yours and Luke2427's standards). I go to a KJVO church. I've been to other KJVO churches. I know many KJVO people.
Here's what Luke2427 says on KJVO:
If KJVO has not been divisive then NO doctrine in history ever has been. KJVO is a new doctrine invented by people who do not CARE about what the rest of the Body of Christ has ALWAYS believed. This is the same attitude that all heretics have possessed. It condemns all Christians who use other versions as either lost altogether or replacing the Word of God with evil perversions of God's Word. These Christians are ostracized and condemned. That is the absolute ESSENCE of divisive doctrine, i.e. heresy.
KJVO brings into question the orthodox view of inspiration and replaces it with a weird, twisted view of double inspiration. The idea is that God did inspire the original words then he did it again about 1600 years later with the KJV. That is simply not the orthodox view of inspiration- at ALL.
So, let's break down the arguments.
1. KJVO is divisive. Something is divisive, so it's heresy? Please, let's move on.
2. KJVO is a new doctrine invented by people who do not CARE about what the rest of the Body of Christ has ALWAYS believed. New doctrine? well, considering that modern version didn't exist until somewhat recently, it sort of has to be new.
3. It condemns all Christians who use other versions as either lost altogether or replacing the Word of God with evil perversions of God's Word. This is simply false. KJVO does not say that people are lost if they use another version. They may say that other versions are perversions or not accurate translations of God's Word, but this is a far cry from basing someone's salvation on a particular version.
4. KJVO brings into question the orthodox view of inspiration and replaces it with a weird, twisted view of double inspiration. Simply not true. Double inspiration is something held by a very few, very limited, and very fringe group of people. The vast majority of KJVO do not hold this view. Even the "Sword of the Lord" folks that Luke2427 like to rail against don't hold to double inspiration (see article on God's Word in this Sword of the Lord http://www.swordofthelord.com/SwordWeb.pdf).
