When I was in, pedophilia appeared to be a ridiculous accusation by apostates. You can get disfellowshipped for sex, drugs or even smoking... obviously, you will get disfellowshipped for pedophilia. However, I had never considered that most people who get disfellowshipped confessed to their sin. They'll confess to sex, drugs and smoking, but pedophiles are a different breed. Most of them will deny, even when confronted by their victims. And so, the two-witness rule, coupled with the fact that elders don't call the police make it a pedophile heaven. The end result is crazy when you think about it, cause there is no doubt that they do hate pedophiles. The problem is their unwavering adherence to their policies.
Hence, the key is to tell them that there are flaws in the policies that work against them. That no one doubt that they hate pedophiles.
