This were we have to accept culpability as a whole people. WE Jehovah's witnesses wanted Armageddon on that date then so we went beyond ourselves. This is not "Them and us" Passing the buck to shepherds, it is simply just not taking on responsibility for our own decisions. Hearsay and reading it into wt's that do not mention the date at all, is just silly.
You cannot construct an official doctrine out of hearsay and expectation. (Well you are obviously trying to do exactly this but your Bias is obvious by the way you are going into it, looking for it. Reading into warnings about Armageddon which we do all the time as particularily relating to 1975.
I could use any watchtowers talking about the imminence of Armageddon to construct an argument for every year since they started writing them.
The facts are that we as witnesses think Armageddon could happen now at any time and we need to be ready and on watch for it at all times as we are in the "lasts days" right now.
