The entire time I was a mormon, the leaders would warn us to not listen to opponents of the church. They warned us that they were evil, they were sinners, they were tools of the devil.
We were warned that although people who opposed the church would say things such as, 'there are significant changes to the BoM' the leaders in the church would tell us that only minor spelling errors had been made.
You have to see this, then decide for yourself:
How can you still believe in your leaders, who are not honest with you?
