false logic by lds church "prophet" gordon hinckley - black or white; 100% truth or 100% fraud

this is taken from page 5 of an 80 page letter by Bob McCue to Jeffrey Holland and is a good example of false logic used by even the (now deceased) "prophet" of the lds church:

I note in particular the nature of Pres. Hinckley's "black and white" argument, which is an oft- repeated Mormon leadership theme. This is nothing more than a false dichotomy that performs the function of a debating trick, except he uses it on people who are willing to accept almost anything he says. How can anyone who has experienced the good side of Mormons conclude that Mormonism is 100% fraud? Therefore, if it is either all truth or all fraud, it must be all truth. This is the conclusion toward which Pres. Hinckley directs as many people as possible. ... I cannot think of anything in life that is as simple as Pres. Hinckley represents this particularly complex issue to be, and my review of Mormon history and theology has brought me the almost certain conclusion that there are serious inaccuracies in the story the Church tells, and pervasive pockets of error within the LDS tradition that continue to influence it today. In short, Mormonism is a mixture of good and bad, truth and error. It is grey. But nonetheless, Pres. Hinckley attempts to win the debate by the manner in which he frames it, and due to how he is trusted, he will be effective in this regard with respect to many people, and was effective until recently in my case.
