These people are sick in the head.
I visited DU this morning, just to enjoy a little schadenfreude, but after about 3 minutes, I just couldn't stand it anymore. The main thrust seemed to be that there really was no Al Zarqawi, that he was an invention of the Bush administration to keep the country angry at the insurgents. Either that or that he is real, but isn't really dead. Those people are simply nuts, there's no other word for it.
