Sevan, you made this comment: "I was a believer long before encountering the Jehovah's Witnesses and I will be a believer for the rest of my life,"
Maybe it doesn't matter to you, but that comment really defines you as a close minded person. It's not unlike the comments made by JW's that they will always be a JW.
When I first left, I read and read on forums without making a comment. IMO, the real value for believer-non believer debates is not for someone like you who already has their mind made up, you will just get offended. Challenge to your beliefs will be taken personal. But for those lurking who are new to the world of being able to think for themselves, it can really be enlightening. For me, as I contemplated these debates, discarding belief in invisible beings I was raised with was my only choice. But it is not a choice that cannot be changed with new evidence.
