Can you help me to find more/less comprehensive set of links that
include a more/less credible "dirt" on Michael Moore or his movies?
Of course, you are not obligated to proof credibility - just
make sure that it looks credible (sort of like a "dirt/truth" on
others in his movies). Please note that I am not asking for a
personal/private matters (after all it is against your rules and
against mine as well).  I need only something related to his work
and/or public life, something that can discredit either his
professionalism or his honesty, etc.  Thanks in advance!

There are only a handful of websites or sections dedicated to Moore
which don't just copy each other's content, so I've tried to include
just the more original websites. You may know some or most or all of
these already:

http://www.moorewatch.com/
Probably the most popular and well known anti-Moore site

http://www.michaelmoorehatesamerica.com/
An upcoming movie's website that "isn't a hatchet job" on Moore but a
movie that will "look at Michael Moore?s claims about the country, its
people, and our way of life."

http://www.moorelies.com/
A weblog that contains a number of items that do not make Moore seem
like a particularly nice or honest fellow

http://www.bowlingfortruth.com/
A website dedicated to Michael Moore's documentary Bowling For
Columbine, which challenges many segments of the movie and Moore's
honesty in putting it all together

The rest of the links are mainly articles which contain stories and
opinion that   take on Moore.
