As an ex-jw it was a surprise and reassuring to see that yet again, so many things portrayed to us as the indesputable truth, was actually a matter of popular opinion or doctrinal bias, etc...but in reality unknowable.
I hear ya. Subjects like this illustrate to me just how much the WT during the days of Rutherford and onward would make a stink over anything for the pettiest of reasons. That same mentality is present within JWs today. Arguing over whether Jesus was impaled with or without a cross-beam is like debating whether the wood used was timber or cedar. I can understand the WT's argument against religious paraphernalia and idolatry regarding crosses, but to argue over a cross-beam is just retarded. By making such an issue over the cross-beam, their points about idolatry and paraphernalia gets lost as a result.
