If there is a dispute, it is possible to write a statement which covers both points of view...

"...there are two schools of thought with respect to blah, on one hand blah, however some ppl believe blah..."

I think ppl would be surprised at how willing others are to avoid conflict and cover all points of view, especially when evidence is provided for both of these, even if that evidence is common practice and documented experience.

Remember it is a document that gets developed, rather than a collection of time-stamped personal comments like those seen in forums.
