I was just thinking of starting a topic like this! I was talking to a local elder as part of my job on Tuesday, and I'm going to be seeing him the same way every week for the next few months. He looked a bit dubious when he saw it was me who was going to be escorting him, but we got on fine. We used to get on very well when we were in the same hall 5-6 years ago, he was a ms then and is not much older than me. He was very friendly, and concerned that I had been cut off by my family. He seemed visibly relieved when I told him I still had contact with them for 'neccesary family business' and was not just given the cold shoulder. I mentioned that I had tried to get reinstated for 9 months, but had given up after that. He was interested that I still have jw issues that I think about, and wants to call round and talk to me about them.
I plan to ask about why its wrong for Ian Huntley to kill 2 innocent 10 year old girls but brilliant for Jehovah to kill millions of innocent 10 yr old girls at armegeddon. Why does Jehovah allow wickedness, seen as the universal question of does man need god to survive was answered in Genesis 9 about confusing the languages in Babel. And why it was ok for the Watchtower to have a political affiliation with the United Nations, but wrong for jws in Malawi to have a political affiliation, the result being that many were beaten, raped and murdered. Depending on how that goes I might bring up the child abuse issue, but I'm not too keen to do that because I know it would hit very close to home for him.
I prefer simple hardhitting points rather than doctinal matters where you can get bogged down with minor details.
