So the real question I see in the forum posts is whether genetic mutations are a form of disease anyone has seen "melt away".
"Genetic" as I understand the term means that you inherited something from your parents. There is always a lot of "recessive" talk mixed in, but basically if you are a dwarf, then your parents were drawrves and, accordingly, your children will be drawrves. Oh, wait---it doesn't happen like that, does it. :)
Medical doctors don't know what disease is and they don't know where it comes from, hence "genetic." Similarly, if they can't figure out what your trouble is, it is awfully easy to say it's "in your head" and send you off to the psychiatrist. So, all in all, they dearly love terms like "germs," "virus," "prion," "mental," and "genetic." It gets them off the hook. And remember that the drugs they dispense so freely never address mineral deficiencies.
My thought is that if someone who follows RBTI closely, but suffers an unyielding disease, then begats a child who follows RBTI closely, but who suffers the same disease and who has, in turn, a child who follows RBTI, but still suffers from the disease, then, and only then, you have something we can call "genetic."
But not before.
(*) Three quotes give added insight to this question. First, in the Alphabetical Reference Manual we hear Reams say, "I do not believe in hereditary diseases; I do believe in hereditary weaknesses. Second, we have Reams saying in the Reams/Black transcript, "I do not believe in hereditary diseases at all. I believe the parents feed the children on the same food that made them have their problem and therefore, they become a child of the same disease as their parent. Third, the Anatomy tapes transcription records Reams involved in this back & forth: MANTHEI: There is a condition that occurs primarily among blacks, sickle cell anemia, and whether it’s a genetic problem or a dietary deficiency. REAMS: Dietary. MANTHEI: From a deficiency of calcium, primarily. REAMS: Basically, yes.
It is important to think clearly about what is being said. Your genes can pass you a weakness (or predilection) to a disease, but not the disease. Reams evidently felt that diet could prevent or reverse the one.
