Ooh, this reminds me! When I was... I forget how old now, or even if I was in middle school or high school, Mom and I found a battered copy of Millennial Dawn in a used bookstore. We were really excited to take a look at some JW history, only to find such nonsense inside that we sort of looked at each other confusedly and shrugged.
For me, the publication that helped wake me up was the "Creator" book, the one with the nebula on the front. Does anyone remember that one? They were fixated on Fred Hoyle's crackpot theories in the early chapters and kept trying to science the shit out of the Bible with varying degrees of failure. I was a high schooler earning mostly Bs at the time, so hardly a mensa member, but even I knew I was reading complete and utter bullshit and the "logic" was just not there! When it became a book study book, it was sheer torture for me, ugh!
