"Why haven`t the Major religions of Christendom exposed J.W.`s as the true Apostates"
In the 1970s when I was a teenage Witness there was an organization named Christian Research Institute (CRI) which was highly aggressive against the Witnesses. They would come to the JW assemblies and try to pass out literature.
I remember, on the day that I was baptized at Dodger Stadium, leaving for home in a school bus full of Witnesses. I saw the CRI people aggressively trying to flag down our bus down waving literature in their hands. The bus driver stopped out of curiosity before they realized who they were. I was curious so I looked out the window and reached out for whatever it was that they were waving. You should have seen the enthusiasm in their faces as they lifted the literature up to me. When I got it, it was a crudely mimeographed/Xeroxed magazine called Not the Watchtower.
When the Witnesses found out who they were and saw that I was getting a copy they were frantically yelling at me telling me not to read it. I had opened a page and saw the most garish type setting. While I only glanced at the article without reading it I saw all sorts of dates and quotes in all capital letters.
