What is moonie? How to use in English

The word "moonie" originates from the Unification Church, also known as the Moonies. This religious organization was founded by the Korean-American religious leader, Sun Myung Moon, in the 1950s. Moon believed that he was sent by God to restore humanity's relationship with God, and he established a series of religious principles that his followers adhered to. The term "moonie" is a pejorative term used to describe followers of the Unification Church. The origin of this term is uncertain, but it is believed to have been coined by members of the church themselves as a way of identifying themselves. The term may have been inspired by Moon's Korean surname, "Mun," which can be easily mispronounced as "moon." Alternatively, "moon" may have been chosen because of Moon's teachings about the importance of the moon in his religious beliefs. Outside of the church, the term "moonie" is often used in a derogatory sense to describe members of the Unification Church as being cult members or brainwashed. However, many members of the church reject this label, asserting that they are devoutly religious individuals who follow their faith freely. In summary, the term "moonie" has its roots in the name of the founder of the Unification Church and is now commonly used as a derisive term by those outside of the church to describe its followers.
