I realize that you are angry, and you feel that picketing will take away some of that anger. It is your call as to what you are going to do, but maybe if it were done in a way so people would be caught more off guard, rather than something that will be in their face, you would get more serious attention. Say for example if you were to print out brochures listing various websites that would get them to think, not websites that blatantly try to denounce the JW's, but websites such as the UN website showing the JW involvement, silent lambs, etc. that would get them to start thinking for themselves in a non-judgemantal way. Think about it, the hotels and restaurants in that area are going to be filled with witnesses, so maybe you could leave brochures at these key locations. It is human nature to be curious, whether one is a Dub or not, and curiosity would likely get the best of a lot of them if they knew they could read the brochure without other people knowing that they picked one up. It would be like finding a porn magazine on the ground, they know how wrong it would be to pick it up, but once again, it would bug them to death to not pick it up, if even to take a quick glance. Once again, Human nature. I think a lot more could be accomplished this way, but, then again, your call.
We can discuss this further if you want. Would love to help you come up with a plan!!!
