The term was created by U.S. journalists in the mid 1970s, as a shortened form of the earlier media-created term "Moonchildren". No relation to Cat Stevens's song Moonshadow has been proven, although an urban legend popular among Unificationists claims that Cat Stevens studied the Divine Principle and incorporated some of the church's themes in his rock music.
After some years of going along with the media's use of the term, the Unificationists did an about face in the late 1980s, when they asked major media organizations to stop referring to them as "Moonies," on the grounds that it is demeaning. The term has since fallen into disuse, except as a pejorative.
The term "moonie", when written with a lowercase "m", can refer to a fan of the animeSailor Moon. This meaning of the term may be more common on the Internet.
If you know about preachers like Jerry Falwell who's taking Moonie money then we need to let those followers know that their Christain organizations are Moonie influenced.
Republican Party knows how much money the Moonies are spending to influence their elections, especially the primaries.
The Moonies are a dangerous mind control cult with millions of followers and billions of dollars.
