No. They create numerous hurdles and problems that shouldn't be there. They prevent people from seeking companionship outside the cancer. They provide answers that are sure to fail miserably. They teach things that are going to be changed a few years later. They teach things that have absolutely nothing to do with present day people. Their policies lead to stagnation.
And, the Asleep! is no better. Those things teach crap science, often out of context or blatantly wrong. Accounts of the Flood are so numerous (and blatantly wrong to anyone that understands the principle of buoyancy), and quite a few threads are up about that. The Young People Ask: Answers That Do Not Work (Parts 1 and the new 2) all come from the Asleep!, and those answers are crap. Certainly, they do not meet my standards.
