Which that debate PROVES to not be the case!
And even if it were the case, the fact that the KJV is written in a version of the English language that is four centuries old is sufficient, by itself, to make at least the New King James a superior English translation (i.e. there are likely several others that are just as good) because English is not like Latin, where the language is no longer in common use and so words do not change in their usage and in meaning. On the contrary, English is the most used language on the planet! As such, it is an evolving language that has changed in very substantive ways since the 16th and early 17th century. Indeed, the fact that every modern translation is not superior to the KJV only goes to demonstrate just how poor many modern translations are. But, anyone who knows enough about the issue to know what the Texus Receptus is, has no excuse to use a more modern translation like the New King James, if one is available to him.
The New King James isn't even all that new any more! Of course, it is in comparison to the KJV, but just think about how much our language has changed since 1982 when the NKJV was first published. By the time its half a century old, (less than ten years from now) it'll be time to revise it again. In fact, its probably passed time already, given the speed at which the international language of English evolves.
By the way, congratulations on writing three whole sentences in a row! Wow!
