Fear the Scarf! If it’s got a checkerboard pattern, it must be a keffiyeh, and those are bad for some reason. Just ask Dunkin Donuts:

Does Dunkin’ Donuts really think its customers could mistake Rachael Ray for a terrorist sympathizer? The Canton-based company has abruptly canceled an ad in which the domestic diva wears a scarf that looks like a keffiyeh, a traditional headdress worn by Arab men.

Some observers, including ultra-conservative Fox News commentator Michelle Malkin, were so incensed by the ad that there was even talk of a Dunkin’ Donuts boycott.

‘‘The keffiyeh, for the clueless, is the traditional scarf of Arab men that has come to symbolize murderous Palestinian jihad,’’ Malkin yowls in her syndicated column.

For her part, Malkin was pleased with Dunkin’s response: ‘‘It’s refreshing to see an American company show sensitivity to the concerns of Americans opposed to Islamic jihad and its apologists.’’
