UBF has claimed repeatedly over the decades that its reputation as a destructive group has come about through unspecified cultural differences and misunderstandings (UBF being a Korea-based group). Those who cite the cultural differences excuse have in mind UBF's most visible and controversial practice, the practice of "marriage by faith," i.e. arranged marriage. But when pressed about it, the same people will claim that "there is no arranged marriage in UBF." Also see, http://voy.com/60734/10294.html.
(BTW, arranged marriage is probably as common in Korea now as it is in America.)
