The implication of the OP is that if you do not set up protest signs and actively demonstrate at your local KH, you are not "in the game." This couldn't be farther from the truth.
I have effectively reasoned with my ex-wife and her elder husband (now a former elder). I have gotten my son see the hypocrisy in the organization. Guess what, that's 3 people I've helped and I have made zero signs! I have held zero demonstrations, and I would think this gives me a higher percentage than any disruption of someone else's worship.
It may not be illegal in the US to demonstrate at a religious gathering, but in my opinion it is reprehensible!
