Don't stop the showings of this! You're playing right into their hands. When you censor the showing, you are telling them that you believe that it is true and you are trying to hide it. Let them show it - just be there with any of the myriad viewer's guides that refute all his obnoxious claims.
You know how Kerry tried to stop Sinclair from showing the anti-Kerry movie. He didn't want the truth to get out. Whether it's true or not (which I believe it is, btw) his suppressing it makes it look true.
I have a great viewer's guide for F9/11 in PDF form. I can't remember the website I downloaded it from. If anyone wants it, i'm happy to email it.
