I'll just come in and muddy the waters a bit.  I actually have no stance  on Michael Moore, since I haven't exposed myself to enough of his  output to judge.  My input is solely based on defining truth.  Truth is  in the eye of the observer, unfortunately.  If ever you ask four people  to give an account of an incident that they all witnessed together,  you'll get a different observation from each of them.  Because we are  all individuals, we tend to give different weights to alternative  things.
