He is right. The Mormon leadership is very skilled at tailoring the message. You will see it here on FR (or did) where Mormon converts will actually espouse their old Christian beliefs that contradict LDS teachings and think them part of the LDS. No one will “correct” because they are after the money, theology is irrelevant.
They also practice the “Milk before Meat” approach, leaving the really weird stuff for after you are caught in the web, if at all.
