3. I love reading about mormon history but have never met an actual mormon. Are they as nice/do goody/wholesome as they are always represented? Do they say regular cuss words or things like "crumudgeon"?
My wife grew up mormon and left the church but a lot of her family is still Mormon. They're pretty nice but have an insanely insular culture, for the most part they don't socialize with non-mormons and like my wife's aunts are amazed when I'm around them being a nice person with kids who aren't demons. But here's an anecdote about cussing:
You know the card game Bullshit? The family plays it, but they don't call it Bullshit. Or even BS. They call it BC and made it a point to make it clear that the "C" stood for "crud" and not the other "c" word. (Crap). Granted these were like kids but it was funny.
I too married into a Mormon family. My wife and a couple of her siblings still identify as Mormon but just do normal USA living. They are considered Jack Mormons as I understand it. I just treat them as a whole with respect like I did my deeply religious Catholic grandmother. I did get to amaze some BYU coeds in OKC at the 2010 tourney with my Mormon knowledge while being utterly PAK'D.
