One only need to consider the fact that these guys devote so much of their time to convincin people they are white to see they are dirty sand niggers (big up, indo-greek, pakizzz!).
Alternatively, pakhtun can also refer to the people east of the durand line. These people dont devote so much of their time to showin how proud they are. Instead they get down to joinin punjabis, and the rest of pak in whoopin indian a**. Combined with punjabis baluchis, they are one of the martial races of the indian subcontinent.
