> However, (also FYI), adherents prefer if you refer to the church as "The Church of Jesus Christ of Latter-day Saints" and members of said church "Latter-day Saints" or simply "Christians".

The first for members is problematic (especially in speech, where there is no equivalent to capitalization to distinguish the proper nouns from a combination of common words; and plenty of people discussing “Latter-Day Saints” would very much not want to endorse the idea that the people referenced are “latter day saints”.

The latter of those is even more problematic for somewhat similar reasons, since there are lots of other people who identify as and are commonly known as Christians, so it's not particularly good to distinguish Latter-Day Saints. Especially given that the boundary large groups of Christians who disagree on, well, nearly everything else draw around the boundary of “Christian” excluded Latter-Day Saints.

> Calling Latter-day Saints "Mormons" is like nicknaming Muslims "Mohammeds" or "Qurans" or nicknaming Islam "the Mohammed Church" or "the Quran Church".

Or, to use a less hypothetical example, it's like calling Muslims and Islam “Mohammedans” and “Mohammedanism”, respectively.
