"Maybe an independent adjudicator to say who is right, who is wrong or whether a compromise is available?"

The problem DtG, is that if we had a resident PhD in philosophical logic who ruled on the various arguments, it would do little good, as the ultimate defense is something like.."Well, my position is 'right', no matter what your expert says about how I phrased it."

And there is a certain force to that. Humans are the only animal that can rationalize and adopt implausible, inaccurate and contradictory positions and then base entire political, religious and aesthetic schemes on them.

*I* can use the pages Acme listed... and various others... to show flaws in many discussions... and have done so in the past. I had many classes in logic & philosophy in school, but I can still only point out logical fallacies to those who care to listen. *shrug*

SUBJECTIVITY is one of the most powerful forces in the universe of human discourse.
