Hi minimus,
I was fortunately, never in that situation. However, had I been or known someone who was treated unfairly by local elders, I would definately speak up. I would try to get help from anyone who would listen. It wouldn't matter to me if they are DF or not.
The reason so many abuse victims don't get help, I think, is because they fear they won't be believed. The feelings of isolation from having their complaint dismissed by elders, I imagine, could be overwhelming. Fortunately there is Bill and Silentlambs.
For everbody out there who has been a victim and is a lurker: Don't hold back a complaint against someone. Bill is the same, DF or not and he is there to help you. He has put everything on the line for that purpose. You are not alone.
