No, I don't actually think James White lacks balance or has monovision.
However, his most recent Dividing Line focused solely on responding to a British charismatic Christian about same-sex marriage.
If someone were to listen to only one single Dividing Line broadcast like that one, which focused on narrowly-focused subject matter,
if someone were to refuse to listen to any rebuttals on his part or search out whether he has written or spoken on any material that's not related to conservative Christians talking about same-sex marriage,
one could say that James White is an "unhinged little micro-group" (after all, there are two men that run AOMin, which is a very, very small group, but still a group) that lacks balance vis-à-vis his churchmanship. After all, I didn't hear him say anything about his church membership or anything during the entire Dividing Line broadcast. Not even once! He had a whole hour to talk! He could've even done a jumbo or mega DL, thus taking longer than an hour.
Could not one say that he is a "one-string banjo, zealous for the one note he has learned to play on what is supposed to be the orchestral symphony of God's truth"? Couldn't one conclude that his narrow focus is "just sad"?
Again, don't bother me with evidence of the other things he has said or written about. I'm only going to pay attention to a small slice of life and intentionally and willfully ignore the rest. I'm going to insist that White is a caricature so that I can dismiss all the other things he says and pretend he has monovision on this topic of what British charismatic Christians think about same-sex marriage. Then I'll berate him for being a one-string banjo; that way I can be safely pre-insulated from anything else he might say that might ever convict me or persuade me to change my ways.
And if you still cry foul, I'll just say that I learned my method from White himself.
