Theyre similar but saying that they (they including punjabi pakistanis) are "indistinguishable" is retarded.
despite being a punjabi, why do persians (and once an afghan) keep asking me "are you persian?" One time a homeless guy started calling me a terrorist. His friend asked "why you calling him a terrorist?" and the guy goes "he looks like a Muslim". Other Pakistanis are almost always able to tell that Im a fellow countryman before even asking my name.
The only people that think Im Indian are retarded cumskins and gigashitskinned high AASI pajeets (of which you are the latter).
