Interestingly, cults generally avoid recruiting people who will burden them, such as those with physical disabilities or severe emotional problems. They want people who will stand up to the grueling demands of cult life. If someone is recruited who uses illegal drugs, they are usually told to either stop using them or leave. To my knowledge, there are few people with disabilities recruited in cults, because it takes time, money, and effort to assist them. People born into cults who develop disabilities are often distanced and sent to government welfare programs.
JWs won't allow such people at Bethel, but they will recruit them as regular members and take their contributions, field service hours, and utilise any special skills.
