the KJVO myth has absolutely NO Scriptural support, & besides that, many of its man-made points are wrong, such as "The KJV is perfect". We've discussed several of its goofs & booboos on this site.
And remember the thread I started about the KJV's being a "Model T" version? Well, that fact is still true. The KJV was made for the British Anglicans of the 17th C, and God has caused newer translations to be made for today's English-users. (As well as translations in other languages for other peoples.)
A story I've told before: I had a neighbor who was a doctor from South Korea, & he was no master of the English language, and was also a new Christian. He asked me if he could borrow a Bible til his Korean-language copy arrived . Without thinking, I handed him a KJV.
A coupla days later, he called me & said he was greatly distressed by the passage "suffer little children". I explained what it meant, & quickly brought him a copy of the NKJV, which does not have the KJV's archaisms.
If one feels more-comfortable with the KJV than with any other version fine, long as one doesn't believe or spread the pack of lies of the KJVO myth.
