> I think you are unfairly raising the bar on the OP by calling for more rigor. If you think it's anecdotal fear-mongering then you must also object to the original responses, as their individual experiences are also anecdotal, and perhaps even anecdotal whitewashing. Their advice did not include any real evidence either.

Oh, I do! I was trying to allude to that by including "fairy tales" in my first comment, but I should have been more clear.
