For a start, members of the Taliban (note the spelling and use it in future) are united by extremist religious views- not by race. Therefore, there's no such thing as a "Talaban accent", members of the taliban could speak the queens english- take for example Richard Reid, the half-English, half-Jamaican man who tried to blow up a plane with bombs hidden in his shoes- I don't know the details of his elocution but he wouldn't have been speaking in a middle-eastern accent.
In a case a couple of years ago, a woman in France had her face bitten off by a dog- and had to receive a face transplant from a recently deceased person in order to survive. If your wife, were to suffer a similar trauma, and need a face transplant, and the only face available for transplant was that of a middle eastern woman- would you deny your wife life for your racist views? Or would that new face turn your wife into a terrorist? What does someone's appearance or accent have to do with anything?
