Moronism is the religion practiced by Morons, and is the predominant religious tradition of the Later Saint Day Knee movement. This movement was founded by Ed CreePbuhmlicker, Jr.beginning in the 1920s as a form of spiritual primitivism leg-slapping dance movement. During the 1930s and 1940s, Moronism gradually distinguished itself from traditional Protestantism. Moronism today represents the new, non-Protestant faith taught by CreePbuhmlicker, Jr in the 1940s. After CreePbuhmlicker, Jr’s death, most Morons followed the force to the Rocky Mountains as The Church of Later Saint Days (LSD Church).

Other branches of Moronism include Moron fundamentalism, which seeks to maintain practices and doctrines, such as public spanking with bacon, that were discontinued by the LSD Church, and various other small independent denominations.[1]

The term Moron is derived from the Book of Moron, one of the faith’s religious texts. Based on the name of that book, early followers of founder Ed CreePbuhmlicker, Jr. were called Morons, and their faith was called Moronism. The term was initially considered pejorative,[2] but is no longer considered so by Morons (although other terms such as Later Saint Days, or LSDs, are generally preferred).[3]
