We have a saying where I work, "If it isn't written down, it didn't happen." And in so many ways, that's proven true. While lots of stuff is said at work and instantly forgotten, my history in WTland seemed to be that lots of stuff is said and instantly gets completely twisted in the JW rumormill.
So someone gets announced at a KH meeting attended by a handful of people. Then the word is supposed to get spread to all the others that had better things to do that night. What was announced? Did they say, "Don't talk to him, because he's disfellowshipped for writing a book exposing WT teachings as wrong"? Why don't they get clear and put it in writing in a public place?
Oh, right, they don't do that because they're a cult that's afraid of lawsuits.
Next you can write a book about your experiences upon being expelled from a 19th century apocalyptic lying cult.
