God-Delusion, welcome to the board. My advice is make sure you want to be disfellowshipped before you let them do it. If you do, great for you, but if you don't, then make sure you avoid the magic phrase, "I don't believe in the Organization."
Just keep on saying you have questions, but you love Jehovah and his Organization. They will have a hard time disfellowshipping you, you can even write to Bethel or talk to the C.O. In order for them to disfellowship you, you have to tell them you no longer believe in the Organization, or the Faithful Slave. Remember that even saying you don't "believe" is grounds for disfellowshipping now.
I almost got in major hot water a few months ago for bringing up stuff at a family WT study. A couple of friends were there too. I was able to stay in by emphasizing I still believe in the Faithful Slave. Some still avoid me, but others don't.
So just MAKE SURE you want to be disfellowshipped before you try and teach the elders anything. They are not there to learn anyway, in their point of view. You could ask them to help you do research, and maybe get them to think, but its a pride thing for most elders, not a doctrinal thing. You could prove everything to them and they won't accept it. That's how I was.
Anyway, I wish you the best.
