“That’s strange, I’ve known about this massacre since I was a child (read it in a history book).”
I’m surprised to hear that. Only one state (Arkansas) has included the Mountain Meadows Massacre in it’s school text State History book. To my knowledge even that one was only recently added (a couple years back) by Dr. Burr Fancher. I’d be interested to know what history book you’re referring to.
Strangely, it is one of the FACTS about MORMONism that in it's HASTE to ignore or bury the 'problem' of MMM; there is not a lot of whitewash spin put on it by the church and most searches about it turn up more truth than fiction!
HIGHLY unusual in all things MORMON.
