Looks like the JW drama circus just came to your town!
She obviously expects you to assume your position as a pitiful, wayward fool (in her eyes). Gawd I have no tolerance for that. In similar conversations I have gained enourmous satisfaction by taking a tone that essentially conveys:
"How stupid do you have to be to believe....
- God has alway had a Faithful and Discrete Slave yet for some strange reason they were nowhere to be found when Russel was around - or when the Bible Canon was needing to be assembled.
- The Society is directed by God yet makes bogus doomsday predictions over and over again.
- God intend to kill 99.9% of humans because a talking snake told a naked lady to eat a piece of fruit
- All of Earths animals were on a wooden boat just 5000 years ago
The list goes on, but you get the idea. She's a moron stuck in a cult that ruin families over loony beliefs like this. I've only managed to see one person exit the silly religion. I'm not sure if I had anything to do with it, but I do recall my healthy doses of ridicule on sheer stupidity of their logic had some effect when we talked. He initially assumed a similar condescending pitiful tone when we talked. It took a couple of whacks with the "ridiculous club" and I sensed he realized just how dumb his position was.
