I don't think most of you guys are being fair. If you were to confront them directly, blast them with an array of questions about their core beliefs do you really think they would respond? Confront people with a silly joke and they are a much more open.
If they are on the defensive because they think the person asking the questions is an apostate or some nobody in a congregation then you might be right but it shows that the lack of openness is endemic. The defensive nature of Witnesses when challenged is repeated time and time again.
What if you met Morris as a householder on the ministry? His response would be different if he thought he had a potential fish on the line. Why would his reasonableness be any different when asked genuine questions even if it is by a journalist or a known critic and apostate like Cedars? Because the WTS revels in it's persecution complex. The WTS does not like debate. The WTS justifies a lack of transparency on the basis of spiritual warfare. A clear demonstration of this was there for the taking.
Don't get me wrong, I am not saying the call was worthless or even that petty. Just the fact an apostate can get that close on the phone is a pretty remarkable achievement. I just think that perhaps the opportunity to get something that was not in the least bit flattering to Morris was there.
