I thought that your information on your first visit was interesting but a little inaccurate. I am also disfellowshipped and working towards reinstatement. All that I really wanted to say is that it takes more than one meeting or Memorial to truly see what JWs are all about.
As far as "whole passages of the Bible being completely ignored", it is just not so. We study each book in full very carefully on a regular and weekly basis. We do this to have a full understanding of the whole context of what the Bible has to say. As far as the Memorial goes they give a talk using the passages that we may all be familiar with, but it is to remind us all of what Jesus did do for us. However in the week prior to the Memorial there were scriptures in the Daily Text that we were encouraged to read that gave the full context of what happened prior to Jesus death.
I am not going to say much more, but I can say that further looking at the Witnesses is something that I would encourage before making any other reservations.
