I agree, with the exception of when a piece of information comes from a credible source such as John Palmer (where the phos reference comes from). If someone sees a wild theory online there is good reason to doubt it, but when it comes from a credible source there is less of a reason for dispute.
Even when something comes from a "credible source" you do yourself a disservice to blindly accept it without trusting your own observations and experience. Although the source may have established credibility in the past om some things, there's no absolute guarantee that source is accurate on all things all the time. You need to use your own experience and common sense to see how that advice relates to you.
