Mormonism is an interesting faith. On the one hand, you would expect the church to have a difficult time holding onto its members since its claims are so bold. On the other hand, few members should leave because the church does such a great job of developing commitment. Religion becomes the center of a Mormon's world; they can't imagine life without it.
Recently, I joined Facebook and within days had about a zillion friends. Many were Mormons who were childhood friends. I counted a total of 28 and proceeded to see how many had switched religions. Thirteen out of thirteen women have stuck with the faith--not one dropout in the bunch. The men are more independent: while 12 are the same, two described themselves as unaffiliated, and one has converted to Eastern Orthodoxy. (I'm not surprised that the first two say they're liberals, while the third one is conservative).
So 89% still call themselves Mormon. Now, I didn't know the beliefs of many of my schoolmates, and perhaps I was more likely to learn the religion of a devout person. If this is true, perhaps a higher percentage of mediocre Mormons have switched. Still, I'm impressed at the high level of retention.
Paleocons, HBD-ers, or whoever can learn something from Mormons. If you want to be successful with an unpopular image and message, be organized as hell--or should I say heaven?
