I was born and raised in the Church (like most of us), and I never once heard someone say they were part of the “latter-day saint movement.”
Though I actually kind of like it. It’s a more open perspective that acknowledges the existence of other churches that also claim to be the legitimate continuation of the church Joseph Smith started.
Come to think of it, a bunch of churches claiming to be the only legit continuation sounds a lot like the great apostasy. I’m sure it doesn’t count this time because… reasons.
What is Latter-day Saint Christianity? I was raised Mormon.
