I can imagine after 4 days of this (and having heard him already take a potshot at White, with his 'this is the typical avoidance of the issues' claim toward White, which was completely baseless in the first place...in fact it is most obviously an demonstration of psychological projection!) I can imagine White would be a little frustrated and disappointed. Still, I have a hard time believing that White would do anything in this kind of format which should be apologized for. I'll check back in after I hear the 'offending' segment. Considering the fact that Gregg seems particularly disposed to imagine things that aren't there in Scripture, I'm skeptical.
(UPDATE)
Just listening to the segment which Gregg was all worried about, about 2/3 through the AOMIN podcast. I can absolutely see why James was annoyed. He had EVERY RIGHT to be annoyed at Steve's begging the question and trying to paint him in the corner with fallacious reasoning. James as usual, asked only pertinent questions and attempted to address the issues while being talked over by Gregg.
