As Edroso explains it at Alicublog:
"When Sadly, No! first tauntingly proferred the keffiyah thing to Malkin, I thought not even she is insane enough to actually take the bait. Now that she has, I'm beginning to get an unaccustomed feeling of Christian sympathy for her. What a small, strange world she lives in -- one in which even simple breakfast choices are fraught with peril. What are her lunch and dinner choices like? When she goes to a restaurant, does she peer into the waiters' station and wonder which dishwashers are illegal aliens and wonder which servers are gays who wish to be married? When she makes her own meals, does she claw through the fridge and pantry like Harry Caul at the end of The Conservation, frantically searching the labels for signs of politically incorrect associations?"
