Sadly there are no magic words or actions that if said or performed will wake people up from JW programming. Only when someone has come to a state of mind where questioning the teachings is possible can you start to discuss and show them some of the many inconsistencies, misinterpretations and hypocrisy.
Believe me I know this from personal experience, for years I felt there was something wrong, but buried my feelings. Even when I acknowledged the congregation had deep seated problems I still defended the Org as a whole. Only when I was ready could I see the bigger picture and then others were able to help me see the real truth.
A big protest is unlikely to help people leave the Org and could ultimately back-fire very badly scaring off those who might be able to help.
