The most explicit statements about 1975 were in talks, not in print. In a talk they could say the end WILL come in 1975, and if its in a talk, especially at a convention, it is considered true.
Beards, R rated movies, Avatar and many other things are not printed, yet are unwritten rules. These rules are just as binding as what is in print. If they are called out about it, they can say WE NEVER SAID THAT, just like 75'
Also, to be in print, most of the GB has to agree to its being published. This increases the chance of material being vetoed. In a talk, a GB member has free reign to spout out personal opinions as law without it having to run through an editing process.
One of the GB, I forget which, maybe Losch has gone on rants about american Football. He does not like it. That wouldnt get into print because they would never agree on printing it.
Morris has a hard on pun intended for tight pants for some reason. Maybe when he is sitting down and a handsome young brother is reading the WT Tony cant help but stare at something snaking down the leg of those tight pants.. He dosent like the feelings that he tries to supress coming to the fore, so he goes on rants about it lol
