I've been thinking about this issue ever since I first saw the 'Vengeance Dad' memes.
I think 'Insanity Wolf' would make a good GB member. "Rape = fornication? What is this "fornication" you speak of?" "Became circuit overseer--recommended my good buddies Shechem and Amnon as elders".
'Philosoraptor' could ask good questions about doctrine. "If the faithful slave didn't know what it was until last year, did Jesus wait 93 years to tell them?" "If in vitro fertilization can be fornication, did I become gay when I gave my urologist a sperm sample?"
...But I trust you're looking for something more specific. This is a good idea. "One does not simply question the faithful slave. One does not simply promise that millions now living will never die. One does not simply claim Jerusalem was destroyed 20 years before it actually was in the face of all historical evidence to the contrary..."
