Remember not that long ago when it was frowned upon in the church to say, "I'm a Mormon"?
Good riddance to those days. So much harder to say, "Actually, we prefer to be called members of The Church of Jesus Christ of Latter-day Saints."
Here's a scenario of one conversation from back in the day (aka, like 5 years ago):
(Person A) "So, are you a Mormon?"
(Person B) "I'm a member of The Church of Jesus Christ of Latter-day Saints."
(Person A) "But you're the ones that believe in the Book of Mormon, right?"
(Person B) "Yes, that's us"
(Person A) "Who do people refer to when they talk about Mormons?"
(Person B) "That's usually us. We prefer to be called members of The Church of Jesus Christ of Latter-day Saints."
(Person A) "So if you're a member of The Church of Jesus Christ of Latter-day Saints, why is it the Book of Mormon and not the Book of The Church of Jesus Christ of Latter-day Saints?"
(Person B) "Because a prophet named Mormon was the one who abridged multiple ancient records together"
(Person A) "Do you worship Mormon?"
(Person B) "No, we worship God the Father and our Lord and Savior Jesus Christ
(Person A) "Can I just call you a Mormon?"
(Person B) "No."
