Hi jwfacts
For me, it was the plain and simple age of the internet. At first, I was reluctant to read anything apostate on line as I was totally brainwashed in my view of anything apostate.
In 1995, I remember going in to a Christian book shop and seeing a book about the Witnesses and bought it. I then sat in the car and looked at the cover of the book, but then decided I couldn't read it as this was wrong. So I threw it in the rubbish
What finally drew my attention to apostate material was when a brother sent a link to ancient Babylon photos which I found interesting. I clicked a few links and saw the confusion over the date 607 bce.
This then led me to JWN and the rest is history.
