No , the Q and A discussion is a basic of their meetings. When I was a a Watchtower conductor I used to welcome the interesting answers, I’ld purposely call on those who would add something to the meeting. That is the way we did it in the old days and those who were my mentors knew how to do it and still end on time.
The ones I have seen in recent years seem scared of answers not from the paragraph, I don’t think they have the confidence to know if they are right or wrong.
If they decide to punish someone they will pointedly ignore their hand, letting them know they are in the doghouse.
