It made sense, all the other religions are wrong. The witnesses are preaching the good news of the kingdom and their literature is available everywhere, ... a number of factors that impressed me.
I trusted them too, never checked references, wanted it to be true.
I had friends in the congregation, loved recieving the new magazines and books....
but as the years went on with no armageddon in sight, friends moving away, meetings becoming more and more boring, seeing wrongdoing on the part of elders, etc , it finally started to have an effect and my eyes started to open a bit more and I started doubting more, I saw no evidence of Jehovah's spirit in the congregation.
I gave up going BEFORE really finding out the tatt. And like you kneehighmiah, I think back and wonder why I could not see what was so obvious to others who were not jws.
