Poor Mark Finkelstein. He really does seem to think that anyone wearing a black-and-white scarf is expressing solidarity with the Palestinians.
He did it last December, when Matt Lauer wore one. And he does it again in a March 30 NewsBusters post, in which a college student being interviewed on TV was shown wearing one. The post is categorized as "humor," but Finkelstein seems deadly serious about the alleged threat: In the post's comments thread, he noted: "I don't think there's any doubt this is a Palestinian scarf. What wraps it up for me is the fringe, which is very typical of the keffiyeh."
In looking for a conspiracy, Finkelstein seems to ignore the idea that black-and-white is a popular color combination and, more often than not, a scarf is just a scarf.
