Oh, I seriously doubt they were duped.
You may be correct. The Left's love affair with these cretins just points out what I have known for a long time. (Well, at least since I left the Left behind.) Leftists love the terrorists because the "enemy of my enemy (ie:Bush, conservatives, etc) is my friend." Also, the left is very violent towards anyone who disagrees with them. I've met some so-called "peace-niks" who believe that conservatives deserve to die for denying socialism, communism, and letting the 3rd World wallow in poverty...
