"What about the facts surrounding the failed prophecy of 1975? To say that the Watchtower “never said that Armageddon was going to come in 1975” is also a dishonest and misleading statement. There is printed proof, YouTube videos, and published articles in major newspapers and the Society’s own publications that prove that 1975 was the central theme of nearly every book, magazine and public talk from 1968 to 1975. I was very active at that time and I know the truth. What do you gain by denying it and saying that it never happened?

So be honest with yourself. Are you really doing the right thing by denying the truth? What impression does that leave with those who are on the fence about joining us in preaching the good news? Is it not better to remain silent than to deny the truth? Does Jehovah really need or want you to lie to protect his earthly organization? Can we not admit the truth of our past mistakes and just move on?"
