You be gone.
Just because one claims to follow Christ doesn’t mean they are a true believer. Jesus even warned his followers about that and about false teachers who lead many astray.
Mormonism is not compatable with Christianity. It teaches many things that are contrary to Christianity but adopts the same terms to confuse people like you.
The OP is following the biblical mandate to warn others about false teachngs.
Christianity means belief in Christ, nothing more, nothing less
As you can’t redefine it, I can’t redefine it to say that you aren’t a Christian if you use a Crucifix in your worship as some have done or visa versa.
It is evil to twist definitions and language to fit someone’s agenda.
If you want to smack down on Mormonism, there are 100s of valid reasons without resulting to this bs redefining terms.
