It was NEVER mentioned 'outright' but ALWAYS 'implied'! Back when i was 21, I was dating this guy that wasn't a JW (ooooohhhh....the horror)!
Anyhow, this guy was RARE: mature, non-religious, comes from a GOOD solid family, college educated, never married and no kids! Top it off with him being gorgeous - and he was a serious catch!!!! To this DAY my mom talks about this guy and how she always liked him (and he really got along with my mom too). So my parents hassle him to study - they tell him "If you want to have our approval, you NEED to become a JW" so this sweet man does...he studies with the PO of my cong at the time. Then he just couldn't TAKE anymore...long story short...he quits studying and my young and dumb ass dumps him. Either way, point is that my mom was SO upset by this guy NOT wanting to study anymore that she tells me
"Well, he can't claim ignorance anymore. Once you KNOW Jehovah's name - you are held responsible. It's his LIFE that is at stake, he needs to realize that."
I remember CRYING (yes...at 21 hearing that broke my heart) and threw me OFF because I just could not understand how in the world this amazing man who had never done anything 'wrong' in his life would be killed by a God that WE (as JWs) were touting as 'loving' all because he made a CHOICE not to serve him? He had the biggest heart of anyone I had ever known, and his fate lied in the hands of an org that dictated whether he was 'accepted or not'? That was really a turning point for me...even way back then.
