I can't make it to the meeting, but if someone could record theirs, I would be interested to hear it. One idea for a comment that came to me was simply to keep including the words "mentally diseased" in an even tone of voice, but very clear so someone might be inspired to think WTF? Something like:
I appreciate how the article brought out that those who are no longer in the congregation of Jehovah's Witnesses are mentally diseased. I am thankful that the article has warned me that these people are mentally diseased. If I ever encounter these people, I will keep in mind that they are mentally diseased.
Maybe it's a bad idea, but I just wanted to share.
