You guys are making a mountain out of a molehill about a right-wing blogger who made a mountain out of a molehill.
The fact that a black-and-white kaffiyeh is a sign of solidarity with the Palestinian Liberation movement is pretty well documented. Don't believe me? Read up on it straight from the ultra-conservative
Party for Socialism and Liberation Magazine website.
Now someone who knows this might be apt to wonder when they see a celebrity wearing a black-and-white kaffiyeh if that celebrity just isn't aware of the symbolism associated with it (namely, support of acts of terrorism against Jewish people in the name of liberating Palestine), or if they are aware and it was chosen to show support of the Palestinian Liberation movement. In any case, it's not an unreasonable question to ask.
It just so happens, however, that what Rachael Ray was wearing wearing in the ad was simply a black-and-white paisley scarf which only bears a passing resemblance to the black-and-white kaffiyeh, and was selected by a fashion designer with no knowledge of the symbolism of the kaffiyeg, so this shouldn't have been an issue in the first place, and it's not an issue that Dunkin Donuts canceled the ad to avoid any potential association with such a hot-button issue .
