Hello Mario, welcome to the site and thanks for posting your letters to the GB.
I can identify with your experience since I joined the cult when I was at school in the sixties and left about 1989. I also had curiosity for everything which became stifled by misplaced loyalty to the Watchtower.
As soon as I left I went whole heartedly into making up for wasted time and went to Birkbeck College for a course on paleoanthropology. I read scientific works and joined a university archeological dig to see for myself what the genus Homo was doing in the Old Stone Age. I also joined the Open university and later did other courses at Oxford for mature learners.
I don't know how well one can compensate for the utter waste of time and effort spent on this worthless religion? Your letters truly demonstrate that they have not got a clue as to an academic or scientific appraisal of knowledge. They are content quoting snippets of the Bible to 'prove' a point or to construct JW dogma, it is all so desperately superficial.
This naivete cannot last in the 21st century environment of better education and the cult is in fact is declining in the Western World. For how much longer do we have to put up with it?
(I loved the Mark Twain quote!)
