Yes, I recall assemblies and conventions where apostates were outside with signs and attempting to hand out leaflets. They accomplished little if anything to promote their agenda. In fact they just reinforced the WT's notion of apostates being "kooks".
I understand their desire to help others see the real truth, but those tactics were, IMO, counterproductive. We all come to terms with the borg's flaws in our own way and time. As witnesses we were so indoctinated to fear and abhor apoatates that any attempt by them to contact us was repulsive and scary.
I'ts best to let people figure out the fatal flaws of the society on their own. They are there, and anyone who gives their brain a chance to think will see the reaL truth.
