No.
Then why do you object to those who witness to them.
You may not like our methods, but they DO work. That is how me and several other ex-Mormon freepers left Mormonism and came to the Christ of the Bible. Including at least 3 from the ‘anti-Mormon’ threads alone in the last 4 years.
There is no one method to reaching people and those trapped in pseudo-Christian cults need to see the errors of their group BEFORE they can be loved to the Lord.
It is completely different than witnessing to the ‘unchurched’. You may not agree with our methods, but they are Biblical and they are effective. I have been in ministry to Mormons for almost 20 years (since I left) and have seen it work over and over and over again.
Just food for thought.
