Exactly right, Outlaw.
Trying to raise controversy during a meeting is a self-defeating proposition. All that happens is that everyone in the Kingdom Hall will think that you are just being disruptive and ill-behaved and will not hear anything that you have to say. It's a fast track to being DF'd.
When I was in (so many years ago) there were two occasions when someone tried to disrupt a meeting with an out of order comment.
One was during a public talk (subject long forgotten). Some non-JW visitor stood up in the middle of the brother's talk and said, "May I ask a question about what you just said?" The brother politely asked if he could hold his question until after the talk and the two could meet at the back of the Hall to discuss it. "No, I want you to answer it now!" was the reply. The brother lowered his head for a moment and then looked up. "No. Please hold your question for now. I only have a few minutes left to cover the rest of the material and I do not want to extend this meeting and inconvenience the other brothers and sisters." For a brief moment there was a silent pause between the two men. Finally, the fellow in the audience replied, "Well, OK. I guess that will be alright," and then sat down. After the public talk, the speaker and the disruptive man met out in the parking lot and had a rather long and heated discussion while the rest of us sat through another boring Watchtower study. It certainly would have been more fun to be outside listening to the two men arguing.
The other time was at a Tuesday night book study held in someone's home. One of the sisters decided to bring her non-JW husband along (he might have been driving her). Someone found him a spare copy of the book we were using. He was quiet and sat on a spare folding chair just outside the ring of brothers and sisters. At some point during the study, one of Daniel's or Ezekiel's prophecies was being discussed. He raised his hand and then very forcefully asked, "Do you people really believe these fairy tales mean something? I don't mean to be rude, but this is all baloney. How can you sit there and just read this stuff like it was real? I'm sorry, but you'll have to excuse me. I'll wait outside for [his wife] until your meeting is over. But I can't sit through any more of this." That was it. He got up, went outside and smoked a cigarette. The poor sister was so embarrassed and explained, "He tends to speak his mind. I know he didn't mean to offend anyone."
That fellow saw through the WT BS in 20 minutes. For the rest of us it often takes years - or even a lifetime. That book study was the subject of KH gossip for months afterward.
