bluecanary,
Ask them to explain what happened at the Mountain Meadow Massacre and watch them squirm.
I was bred and born in the Salt Lake City, Utah area. I was raised there, too, through High School. My ancestors were Mormon immigrants and pioneered their way to Utah pushing handcarts from Nauvoo, IL. I know whereof I speak.
Do a little research on the Massacre first, of course. I can guarantee you, they will give an answer as predictable as the JW answer when you asked them about 1975.
Side note: When I was a young child of about 11, I lived in Boise, Idaho for a few years and we attended the local Kingdom Hall there. There was a very old anointed JW lady who had no chin: just scar tissue where the chin should be. In my innocence, I asked her about it. She said, "it happened when I was a little girl, and I wrote about it. I will give you the magazine that has my story." And she did. It was one of those "Wild West" magazines. And I read it.
She belonged to a family that lived in the Salt Lake City area when Brigham Young was the de facto dictator there. Her Mormon family did not like the way he ran things, so they decided to peacefully leave and take up stakes further north. But, no! Brigham Young would have none of that. He sent his henchman and a posse (yes, he did have a henchman. Read up on that part, too) after those families to destroy them or bring them back. Lots of guns were fired, and this (then) little girl had her chin blown away with a shotgun off by one of Brigham Young's soldiers.
I met this woman. I read her story. I have lotsa more Mormon stories to tell you, as I grew up as an outsider dub there. Even Catholics were considered cults in a State which was dominated by another wacko Cult.
We had only 1 Catholic (a girl) in my Junior High School of 1,500 pupils!
