The Church of Jesus Christ of Latter Day Saint (or Mormons) and Jehova witness are just trying share what they believe and make people's lives better. People being rude and making up stupid topics about them is in itself unclassy and shows ignorance and intolerance for a difference in ideas and views. If you just say no thank you to missionaries they will politely bid you good day. For heavens sake people, there is no need to be rude.
