Well, Jim Lee demanded credulity, made the argument from authority (his own authority) and wouldn't let Producer Dave finish his statements. Dave ended the conversation after repeatedly pointing out that Jim was interrupting him. This guy is just another dumb chemmie it seems.
Here's the waveforms from the conversation, Dave is the channel on top, as you can see, Jim spoke a great deal more than Producer Dave did.
If you also take him up on his challenge, understand that he will in fact talk over you and cut you off basically the whole time. We suggest that should you speak with him, you also be willing to end the discussion if Jim does this. There's no good reason to continue a discussion with someone who refuses to let you finish your statements.
Strangely enough, when Dave went on the MadisonStar Moon Show, he was not interrupted or spoken over nearly as much.
