Quote - emotions. He is not constrained by the need to be objective and make only true statements. If you say this:
(A)"...What one perceives to be true or not depends largely on one's own biases..."
and then say this:
(B)"Care to offer well documented (and I do generally demand extensive documentation before I believe very much of anything these days) and various examples?"
how would that be of any use, since your bias -- by your own statement A -- drives your fact were to be discovered in a Moore film, that still does not make him a documentarian.

Oh, blah, blah. Believe it or not, some of us actually do want to know the truth. We are not trying to be post-modernists. We simply know that all you folks out there who claim to have the absolute truth, and nothing but, are just as likely to be lying and making things up as anyone else, or interpreting things to your own liking and benefit, because many that make such claims have been caught doing exactly that.

Some of us just don't have the unexamined self-assurance some of you seem to have about what is true and what is not. I have changed my mind about what is true and what is not on various occasions. I have even done it on these forums here at Renderosity, and I cannot say that about anyone else here I have ever debated, so just blah, blah, blah. Your point is not valid.
