But of course we always do. For one thing, the ability of our missionaries to teach people the gospel is strongly affected by what people think they already know about us.
Controversy isn't always bad for our purposes -- when we take a stand and become known for it, there are those who are drawn to us because of it.
But our mission is to take the gospel to all people, including those who disagree with us, and especially including those who are devoted to activities we regard as destructive to their souls. Christ said that it is not the healthy but the sick who need a physician.
