I agree that fact checking is mandatory. This is an article off the Internet, with all the caveats that implies.
I think the general philosophy and approach of the article is very useful. I'm not convinced of certain statements he makes, but that's par for everything I read online. Even vetted and published materials get the skeptical eye, since good advice for one landscape may be bad advice in another.
I hope that we can discuss gaps or inaccurate statements in the document rather than descending into personalities. It's a much more productive use of time and energy.
(P.S., I suspect you were thinking of household bleach in your example. But I get your point.)
