I am an anti-Mormon, not by choice but by reputation. A few years ago a good friend left the Mormon Church (I never call it "the church" because it isn't) and insisted that she was going to do things differently.
She was going to be conciliatory ("Done that", I said).
She was going to give the full name of the Mormon church ("Done that", I said).
She was going to ask honest questions and not meddle with side issues and hearsay ("Done that too" I said).
All-in-all she was going to be the sweet and charitable person she is in her witnessing.
"It won't make any difference", I said.
"Why not?" she asked.
"Because no matter how you wrap it up, couch it in endearing terms and make it smell nice you will be an anti-Mormon unless you agree 100% with the Mormons."
Nonsense!" she replied.
Sometime later I got a phone call and a plaintive voice at the other end said, "They called me an anti-Mormon. I don't understand it."
I allowed my silence to speak for me. Eventually she asked, "What's the matter with these people?"
They're Mormons", I replied. "It’s all they know how to be."
I became a Christian 24 years ago and left the Mormon Church. I love Mormons and that is why I witness to them. They call me anti-Mormon because I love them enough to tell them the truth.
"Blessed are you when people revile you and persecute you and utter all kinds of evil against you falsely on my account" (Mt.5:11)
I am not an anti-Mormon in truth. Someone asked me once, "Why did you turn your back on the church?" I replied, "I didn't turn my back on the church. I turned my face to Christ and found the church behind me." I am a Christian and I want my Mormon friends to be Christians too.
