So JW's always described apostates/ex-JW as 'mentally deranged" or whatever...and that they were the ones doing crazy things (picketing outside district assemblies, jumping up and shouting at meetings, etc). And most of us have seen that at least once in our lives, right?
Even today...if I were st work and someone jumped up and started yelling, or came in the building and made a scene - I'd label them crazy! Understand that doing the same thing in a Khall will not put seeds of doubt in anyones mind...but will make them discuss your crazy actions (instead of your intended message).
