Like you, I like to be nice to people. I also like the Mormons even though I am non-religious with a Catholic/Evangelical background. They are often very kind, wholesome people, and in my experience, more willing to self-examine than most Evangelicals. What I don’t like is pushy people, and the local Mormon youth have been ambushing me at the corner store asking to tell me about Joseph Smith and pray for me or whatever. After about the third time in two weeks I started putting on a big smile and telling them that I worship "our dark Lord, Lucifer, son of the morning and to bring me more literature because I ran out of wrapping papers. The number of people trying to convert me has probably dropped by 66%! :D

I feel a little mean, but that’s what you get for not respecting a clearly communicated boundary.
