Sounds like you studied theology. I should say mainline Protestants believe in The Trinity. I have a cousin who mixes Far East religions and christianty and calls herself christian, she’s not. I don’t know anything about the other religions you mentioned. I know some about mormons from FR.
I agree but do question the importance of a doctrine not mentioned in the bible and that wasn't formalized until well after the scriptures had been closed?

Same issue with Masons. People who are Masons may call themselves Christians and faithfully show up every Sunday morning at (insert church name) then later head off to the Masonic lodge/temple. A person watching these Masons could become suspicious that they may have some doubts about Christ's sacrifice.

I personally consider anyone who believes in Christ's sacrifice to be a Christian. Beyond that, we get into categories of Christian such as those who believe in Christ's sacrifice AND try to live in accordance with scripture, etc, etc, etc.
And FR reported FACTS from the WRITINGS that MORMONism has produced over the years.
