people who spew such crap actually have a very faint idea of indian civilization, the modern numerals were given by the indians, concept of clinic, health care hospitals came about in india, just read arthashastra and natyashastra, these to manuals alone exhibit indian organization in greco roman periods which was far superior then the later, indians had local govt during maurya period which was not the case all around the world thousands of years later. Indian architecture is now declared muslim, who gave the concept of pointed arch, multi foil arches, minars, the finials which adorn every islamic dome today? it was basically all indian concept, even the idea of crescent mounted on the islamic mosques is a buddhist tradition, all early and foundational islamlic observatories were actually indian in origin. The indians not only exported spices but were the first to discover sugar/refined sugar, all your desserts owe their existence to an indian discovery.
as to the dhoti rant, even the ''muslim'' kameez, kurta is basically an indian dress, only indians used to wear a dress which had two slits on their gowns, this is proven through gupta era carving which shows a woman/dancer wearing a slit shirt like kurta/kameez and an al eruni account also describing a slit shirt worn by the indian females, no where else in the world, such a dress was worn which used those slits so characteristic of kurta or kameez, so even the pakistani national dress has indian origins
i wouldnt even bother about the food, if you thik that pakistani food is persian, arab, just prove it with evidence and not just rants.
