I rejected the Cedar Point Ohio nonsense, when I was in my late teens , in the late 1960's.
I simply could not believe that a Bible Prophecy would be fulfilled in Rutherford and a few followers holding some small Convention, unnoticed by the World.
Sadly I went no further, and did not question properly the 1914 thing until many decades later, I do remember my mother telling me about the Ray Franz thing, 1981 ? and saying "They are saying they do not believe in 1914 !". I recall thinking at the time, "I'm not sure I do either", but still went no further then.
It was years later that I sat down and thought " I'll read the Book of Daniel today, as though I've never read it before, and without W.T. "Spectacles" on ", of course from then on the 1914 thing was blown out of the water, entirely, I researched some more, and shortly after walked away for good. The whole House of Cards that is their unique teachings fell down, just using the Bible,and what it REALLY said !
I was a Lover of Truth, and could no longer associate with a "religion" which taught Lies.
