No they don't. The Roman Catholic church has some issues with the authority of Protestant churches, but don't quite define "authority" the same way LDS do. (To Lds, authority is everything and lack of it = apostasy).
Otherwise, you'd be able to find a recent formal Rome-based document that labels Protestants as "apostates" (you can't). So it's not just the informal Protestant-Catholic relations you cite above that lacks any such labeling, it's also the formal recent Catholic statements on Protestants that lacks any such labeling.
The first Christians were Jewish and were considered apostates. Jewish people today are also, I find, tolerant and respectful.
In one sense, you can apply what I said about Catholics to Jews. I'm sure you can find some early formal Jewish docs that may label Christians in an unflattering manner, but those are recent docs. (And Jews don't consider any such statements as "Scriptural" level revelation from God)
Likewise, Mormons have that statement in their history about the Creeds being an abomination. However, Mormons don’t go around telling people their creeds are an abomination. As a matter of fact, few people even care about creeds anymore.
"Few people even care about creeds anymore"? (Are you serious?). That might be true in Europe, not here. Creeds are not just sunflower seeds you toss out the window. As for Mormons don't go around telling people their creeds are an abomination then what's with LDS training & sending 60,000+ some-odd missionaries to go door-to-door world-wide, where the training inherently focuses on 1 of 3 major doctrines--the apostasy & restoration?
(And, what's with LDS tithing to publish & distribute world-wide millions of copies of the Pearl of Great Price...including multiple-language translations? Next, you'll tell me, "Oh, nobody cares about the Pearl of Great Price or LDS missionaries at their door.")
Many Christians believe that because Mormons do not agree with the Nicene Creed they are so apostate they are not even Christians. They call them a cult.
Technically, Christians would not refer to Mormons as apostates (which implies spiritual infidelity & unfaithfulness) as much as they would use the term heretics, which I would agree is equally unflattering. But if "anything goes" in theology, then a "Big Tent" church = a church not left with many absolute truths. Furthermore, we don't label every non-Protestant or non-Catholic to be a heretic or apostate, because we know we serve and worship a God who transforms us. Again, that can't be said of LDS.
