Think of all those sat there at that section of the convention. At least some will have watched the ARC. At least some will have experienced the dead hand of a poor child abuse handling. More will have a relative that they are shunning or they are being shunned by. Others know of bethelites being laid off.
It will make those that are quietly thinking actually think. Most of those around him will be servants or elders.
If I personally had been sat there, all quiet and bored I would have had to fight the impulse to get up, shake his hand then put my arm round his shoulder and say "Do you think we can find a better way to get through to these people?"
