If I could go back in time kick some one's ass, it would be my own.
I started studying in 1972, I was sucked in by the whole 1975 thing. At the time I was a university student (at Washington State University), I graduated in 1973 and was baptized a few months later. During this entire time I was studying I had access to the university, which at the time had something over 2,000,000 books in its catalog. I never once went there and looked up Jehovah's Witnesses.
As an JW I had many discussions with householders about religion. I only listened to their arguments long enough to plan my next comment.
The reason the vast majority of non-witnesses don't talk to witnesses about religion is because they have better things to do.
