FAIR (fairlds.org)
FAIR may well be the best LDS apologist web site on the internet. (An apologist is one who defends a particular set of beliefs.) FAIR is a non-profit organization dedicated to providing well-documented answers to criticisms of LDS doctrine, belief and practice. If there is a documented criticism of the Church, our Prophets, our history, or our beliefs, FAIR has more than likely responded to it with a thoughtful, well-researched, and well-documented reply. It is a fabulous source for faith-promoting answers and discussions.
