Part of the problem is that people are lazy, and insecure. Clinging to a version excuses them from research, and gives them the confidence they need to go on secure in their ignorance.
So while the rest of us go on in our multiple translations, and our reference books, they can cling dogmatically to their blessed version/ translation, and in the case of the King James often transliteration. Because it's security not depth that they require.
