The fact that anybody made this claim (which is pathetic) in the first place just shows how sheltered and out of touch with reality some of the Witnesses are!.. They may be nice people but they are painfully ignorant.
It also sounds to me like generational ignorance! This is also a consequence of having no contact with non-JWs. Most non-JW people, even if they themselves hadn’t gone to college, know people who have. Surely they heard about studying until early am hours, exams and having to read tons of things, etc… I doubt any of them would ever come to the conclusion that just reading periodical magazines of some religion (with a half-baked article on science here and there) would be equal to somebody’s ‘college education’. 🙄
