This is another potential reason for us to exist. The average Joe Sixpack would never take notice of such things as books missing from library shelves. We notice however and can point out this unfortunate fact. And we can also identify the reason this is happening.
The JWs act just like every other tin-horned dictator and rule making tyrant the world over. They absolutely cannot tolerate even mild criticism, much less the raw, unvarnished truth and that's why books like Crisis of Conscience and all the others go missing from library shevles. These books tell the truth about the JWs, and the JWs can't have that. That is the last thing the witnesses want even though they claim to represent the only channel for the expression of truth on earth today. Truth to a JW is like a mirror held up to a blood sucking vampire. They can't stand the truth.
