You didn't go into deep enough thought if you squeezed that out of what I said. I haven't "reject"ed anything. Questioning why there is no evidence for a commonly held strong recommendation is hardly rejection. Rejection is outright believing that something is false. I am searching for information, and am not comfortable with such strong belief systems based only on word of mouth. At least I can't find anything solid. Can you?
Seems to me in my life I've seen a bit too much common knowledge later prove to be mythic in nature.
