Checked on snopes, its true
Yep, I just checked it out on Snopes too. Apparently there's another little interesting tidbit: "The message was a response to the Muslim group's having handed out free cocoa during a public awareness event about controversial cartoons that depicted the Prophet Muhammad as a terrorist."
Gah, what is with these people having to give free handouts (underwear and Ramen in the case of Michael Moore) to try to get a turnout...
