Would you care to talk about J. Smith and/or B. Young's "revelations" about "someone else's religion?"
Or is that a inconvenience?
There is a difference between stating that your religion contains the fullness of the Gospel with all other religions lacking that fullness and arguing from the pulpit that members of another faith are not Christian and are going to Hell.
You won’t find anti-Baptist/Catholic/Methodist literature in any LDS bookstore. You won’t hear a Mormon leader preaching how evil the Baptist/Catholic/Methodist church is and how their members are going to Hell.
We concern ourselves with trying to live our gospel and teach others what we believe. We don’t spend our time tearing down their faith.
I chose those churches of the top of my head. I’m not trying to characterize those churches by naming them, e.g., all SBC preachers do not preach against the Mormon faith.
