Michael Moore has put up
Fahrenheit 9/11 references. No surprises here for anyone that has read
Dude, Where's My Country, but I guess some people still think he makes this shit up!
Michael Moore and Al Franken both take this stuff seriously. MM occasionally will give you only half the story - hell, he's proud of it. Don't believe him, get your own fact checkers - but when he states something as fact, it is true. AF goes even farther, with extensive fact checking on EVERYTHING he says, since his big trigger is LIARS.
Either way, you can attack their opinions, but attacking their facts is just going to get you into trouble.
