I saw the 1975 excitement first hand in the KH, but IMO, there was a small number of brothers who were skeptical about that date, but they kept quiet, so an not to throw water on the exciting increase in interest and new KH members coming in. Yes, I heard some elder say "stay alive until 75" at a circuit assembly in a talk, they also made an positive example out of an elder's son who quit high school at 16 and became a pioneer- the koolaid was drunk by many back then. I originally thought it was great, but by 1974, I was in the camp of, we shouldn't set dates.
Last year, was the 35th year since I sent in my exit letter to WT headquarters.
You can't cheat death by being a JW, nor can you avoid the consequences of being in a religious cult.
For those PIMO, consider this, God gave you a unique life to live, but JWs have taken that way and substituted their teachings and planned way of life for you- a fake reality. The longer you avoid leaving the KH, the less of your real life will be left to live.
Take your punishment from the KH, be a man and leave with your head held high.
Follow the light of truth- The only reason you haven't quit the JWs, is because you won't publicly tell the truth about how you really feel. Once you start telling the truth about your feelings, the KH will make leave.
