Talking to a brick wall is very frustrating. I like progress, making a difference. If it feels like I am not making any, I find something else to do.
It is also destructive to be negative all the time. The WTS feeds on peoples fears and negativity of the "world" outside the organization. I am guessing that some who leave the WTS carry that negativity out with them, except afterwards it is against all that religious you-know-what. I also have friends that are big in to anti-abortion and animal rights who regularly horrify themselves with pictures of boiling cats or wiggling fetuses. I just couldn't work myself up to such a frenzy. I have been close enough to real evil in my life to deliberately expose myself to more. One of my friends in to the anti-abortion thing chose a new path, which I try to model. She decided to be pro-children instead of anti-abortion. She started Kids Cottage, a place where frustrated parents at the end of their rope can drop off their children while they go get counselling. Stopping the abuse before it happens. It has been a huge success and helped many people.
I do not know how this could be applied to an anti-JW campaign, but for now I am satisfied to study and learn.
