Ninja: Non violent protest should not be demonized. Even if it doesn't cause droves of people to question their religion, it may just reach one person that experiences it. That one person is a difference maker.
I am not sure what you mean by "non violent protest", Ninja. I am going to assume that your comment relates to the recent display by some young, immature men at the Memorial.
A violent act does not need to be defined by whether or not it causes physical injury - many acts are violent in nature by the virtue of aggressiveness. There is a big difference between aggressiveness and assertiveness.
Aggressiveness attacks other people's space - assertiveness is about claiming your own space.
The nature of the relationship between the JW adherents and the WTS is an abusive and controlling one. And, with that in mind, any attacks or aggressive methods only serve to tighten the bond between the WTS and the JW.
So, your comment that "it may just reach one person that experiences it. That one person is a difference maker" is a fallacy. That one person comes at a pretty high price - the aggressive actions required to 'save' that one person can, and does, throw all the other JWs under the bus, who could potentially be reached with more sophisticated methods. For every one you 'save', you sacrifice the countless others who could be 'saved' but instead are pushed into an even tighter relationship with the WTS by that aggressive action.
