Despite their good manners, I dislike when Mormons knock at my door to sign me up for salvation. Whether the product is heaven or a vacuum cleaner, I am not much for salesmen. Can they know what's best for me, who do not know me? At least Mormons wear starched shirts and neckties to warn me I am the object of their calling. More cunning were the undercover missionaries I knew in college, who befriended people in order to convert them. Friendship and proselytizing are incompatible, for the latter requires molding others into your image, while the former requires leaving them as they are. Genuine friendship means respecting your friends enough to let them be damned.
