cluless - I don't feel like I'm being selfless. It takes little effort really, it's more awareness. Remember trying to turn a casual conversation into something about the Bible? Now I just look for opportunities to mention that I was a witness and now I'm not and a bit about why I'm not.
For example, the Holidays made it so easy. I would say how excited I was about getting to celebrate Christmas after all these years (30) of believing it was wrong. Of course people want to know why. I tell them I was in a religion that didn't celebrate, name the religion, and proceed to tell them how shocked I was to discover that pedophiles were hidden and protected in the congregation. I am very friendly and they can see that I am sincere. So when I get to the part about them being allowed to come to their door even though they are known to be perverts that hurt children they usually look shocked themselves. I warn them to be careful because parents of molested children have been told not to involve the police by the elders.
It all depends on how much time I have as to how far I go. I can make a point and wrap it up in 3-5 minutes if I have to.
