Your experience sounds much like a conversation I had with my mom a couple weeks ago. We covered much of the same points and she always had the same defensive answers. Every week they are being warned in some form about apostate thinking and they chalk any independent thinking up to Satan. You certainly can't question the elders or GB, though imperfect, they are doing the best they can. (yeah, right).
My mom reminded me that I made a vow to Jehovah and I'd be breaking that if I didn't listen to the organization. (The org. and Jehovah are inseparable to her too). I firmly told her that I wasn't leaving Jehovah but I'm doing research and I don't believe it's the Truth because I'm finding lies. She grumbled and didn't have answers for that, but she said she's very sure it's the Truth.
So my goal now is to compile whatever misquotes and lies from the WT publications that I can find over the next couple months. I think the kicker for a lot of witnesses would be to see them for themselves in black and white. I'm not going to tackle deep doctrinal issues, though I will share some of the brilliant thinking of Russell and Rutherford. I also won't push the child abuse, U.N. scandals, etc. much cuz I think that'd immediately be dismissed as unreliable or some sort of overblown reporting.
I don't know even then if it will open the minds of my mom or friends, but I'm hoping to at least make them see why I've made the decision to leave and it's not because I'm a lazy or bad person. But it IS our lives we're talking about. Assuming it's coming, could I face God on Judgment Day and tell him I stayed and supported this religion not because I thought it was his true organization but simply because all my friends and family liked it?!
I wish everyone the best in their endeavors. Keep us posted.
